00:05 11 dot com . Hi everybody . My name is
00:08 Alicia In this lesson I'm going to talk about how
00:12 to describe an object dimensions , dimensions means the size
00:17 of an object . All of the different sizes of
00:20 an object . I'm going to talk about a few
00:22 keywords that we need to describe these sizes and I'm
00:27 going to talk about how we make sentences that use
00:30 this kind of information . So let's get started 1st
00:34 . I want to begin with this list of keywords
00:38 for this lesson . So I want everybody to be
00:42 careful about the grammar of the sentences when they build
00:46 these sentences . So first let's look at these words
00:49 . Hear these words are all now sounds . The
00:53 words are length , length , width with height ,
01:01 height and depth , depth . So each of these
01:06 now towns when we use them to talk about the
01:11 size of an object , explain some kind of like
01:15 question . So by that , I mean with length
01:18 , for example , length tells us how long the
01:23 object is , so length you can connect it with
01:27 the word long , Remember though this is an adjective
01:31 . How long is the item length ? Is the
01:34 noun form here ? Similarly with with tells us how
01:41 wide is the object , How wide is the object
01:45 ? So length is ? How long with is how
01:48 wide the object is ? Height tells us how tall
01:54 the object is , how tall . If that's our
01:58 question , we're looking for the height of the object
02:02 , how tall is the object ? My height is
02:05 that's what we would use to talk about it as
02:07 a noun . Not tall , which is the adjective
02:10 form but height . That's the noun form , finally
02:15 depth , depth . We use depth to explain how
02:21 deep an object is . So we might use this
02:24 more for like things where we need to go under
02:28 the ground . Perhaps in some cases it's used for
02:31 talking about buildings like how far back something goes .
02:35 We could also use this to talk about underwater measurements
02:39 or maybe like as you'll see later . Like a
02:41 bathtub measurement . Something that goes down so depth tells
02:46 us how deep something is . So to review length
02:50 is , how long something is with is how wide
02:53 something is height is , how tall something is and
02:58 depth is how deep something is . So when we
03:02 are talking about these points we use measurements measurements .
03:08 So a measurement is the unit that we use to
03:12 talk about these things . So there are two systems
03:16 in the world that are used . The U .
03:18 S . Is one of I believe only two countries
03:22 that uses what's called the imperial system . In the
03:26 imperial system we use inches , which we write in
03:31 a short way , an abbreviation as I N .
03:34 Inches and feet , which we abbreviate as FT feet
03:39 50 inches I N . So there are 12 inches
03:45 In one ft . So an inch is a small
03:48 unit . A foot is a larger unit . There
03:51 are 12" inside one ft . This is the imperial
03:56 system . Now there are larger measurements in the imperial
04:00 system . Yes . But for today's lesson , I'm
04:02 focusing on measurements of objects . So I'm not going
04:06 to talk about the larger measurements . Okay , but
04:09 let's compare this to the metric system . The metric
04:12 system . Most of the world uses the metric system
04:17 in the United States . The imperial system is used
04:20 , but most of the rest of the world uses
04:22 the metric system for today's lesson . I want to
04:25 focus on these three key vocabulary words . They are
04:31 millimeters millimeters which we abbreviate . We make short as
04:36 M . M . We have centimeters centimeters which we
04:41 abbreviate as C m c M . And finally we
04:45 have meters , meters . We abbreviate with em .
04:50 So for reference inside one m . Inside one m
04:55 , there are 100 centimeters centimeters and there are 1000
05:01 millimeters millimeters . So 1000 millimeters 100 centimeters inside a
05:08 meter . So if you're interested , you can break
05:11 down this center and millie to learn more about the
05:15 histories of these words . But that's a little bonus
05:18 point for those of you who are interested . Let's
05:21 look at how we use this then to describe an
05:24 object dimensions to talk about the size of something with
05:27 these words to . So I've drawn this object a
05:30 box for this lesson uh and I have marked here
05:34 20 40 and 60 . So I want to use
05:39 these numbers to talk about the size of the object
05:43 . So let's take a look at a very basic
05:46 way to describe these dimensions . This box is 20
05:52 cm in this case X 40 cm x 60 cm
05:59 so very commonly in english writing and in writing .
06:04 I think maybe from other languages too . We see
06:07 this X between our measurements in english , we read
06:11 this as bye bye . So naturally I would say
06:15 20 centimetres by 40 centimeters by 60 centimeters . And
06:20 if it's understood , if this unit of measurement is
06:23 understood , we might say just 20 x 40 x
06:27 60 or 20 by 40 by 60 centimeters is also
06:31 okay . We often don't need to say centimeter centimeter
06:35 centimeters after each one because everything should be in the
06:39 same unit of measurement . So 20 by 40 by
06:42 60 is a very clear way to say that if
06:45 you're using inches actually , these are the same measurements
06:49 just in inches . In the imperial system , You
06:53 might see for example , a dot in the number
06:58 followed by a couple more numbers . So these are
07:01 the same measurements actually just in the imperial system inin
07:06 . So to describe the dimensions of this box ,
07:09 I would say . This box is seven 84" by
07:16 15.74 inches by 23.62 inches . So again , we're
07:25 using by here , we read this the dot as
07:30 point point . You'll also notice the number or numbers
07:35 before the dot are read as regular by that .
07:39 I mean seven and 15 and 23 . Those are
07:44 red as regular numbers . The numbers after that are
07:48 red individually . So 7.84 , not 7.84 . We
07:56 read it one at a time . Each number is
07:59 read one at a time . 7.84 inches by 15.74
08:05 inches by 23.62 inches . So when you need to
08:10 read these small numbers after the decimal point , this
08:14 is called a decimal point here we just read it
08:16 as point , make sure to read these individually ,
08:19 not together . So this is another small point about
08:23 dimensions . Of course you may see this in centimetres
08:27 to maybe 20.5 centimeters for example . So this is
08:31 how we read these portions of the sentence and also
08:35 a point about reading the numbers too . So how
08:40 do we use the words long and length and so
08:42 on ? So there are a couple of different ways
08:45 to describe this . So as I've said here this
08:48 is very common using just the dimensions like this .
08:51 We can do that . If you want to be
08:54 very specific about your dimensions , you could say for
08:57 example this box is 20 cm long . That means
09:01 the length Of the box . So in this case
09:04 maybe this is 20 for example . Um and also
09:08 maybe it's like the difference between width and length is
09:13 sort of just up to the person who created the
09:16 object . Or maybe it's just for reference purposes .
09:19 So sometimes there's not like necessarily always a rule For
09:23 which is within which is length , but length tends
09:26 to be longer than whip . So for this example
09:30 , probably 40 We would say is the length and
09:33 20 is the width . But for this example ,
09:35 sentence this box is maybe 20 cm long . This
09:40 is how I would use long in a sentence .
09:43 However , if I want to use length , The
09:47 Noun form I talked about earlier , the length is
09:51 20 cm . So notice this sentence and this sentence
09:55 are sharing the same information . The length of the
09:59 box . That's the information . But the grammar of
10:03 the sentence changes . This box is 20 cm long
10:07 . Adjective here . The length is 20 cm or
10:11 the length of this box is 20 cm , so
10:15 note non form and adjective form , length and long
10:19 . Uh they require slightly different sentence structures . Let's
10:24 look with wide and with them . So here uh
10:28 this box is 40 cm wide . This is my
10:33 adjective form , The width is 40 cm . This
10:37 is my noun form . We can do the same
10:40 thing with tall and height . This box is 60
10:45 cm tall , Or the height is 60 cm .
10:50 So again tall is my adjective . Height is my
10:54 noun . So depending on the word I use ,
10:57 I need to make sure my grammar , the structure
10:59 of my sentence is correct . I cannot say the
11:02 tall is 60 cm . That is incorrect because tall
11:06 is an adjective I must use unknown here . I
11:10 also cannot use height in this pattern . This box
11:13 is 60 cm . Height is incorrect because height is
11:18 a noun . I have to use an adjective here
11:21 . It's 60 cm tall . This is correct .
11:24 We use the same pattern when we're talking about people's
11:27 height . So her height is 160 cm or she
11:32 is 160 cm tall . So please keep this in
11:36 mind when you're talking about the object dimensions , the
11:39 sizes of objects . Finally , I mentioned the word
11:44 deep or the word depth too . So you might
11:48 use this if you're talking about like your bathtub .
11:50 For example , my bathtub is 80 cm deep .
11:55 So here deep . Again , this is the adjective
11:58 form to use depth . We would make a pattern
12:01 like this . The depth of my bathtub is 80
12:06 cm , for example . So this is how we
12:09 introduce sizes in English . So important points to take
12:14 away our this by and this point this will help
12:17 you sound more natural when you are reading dimensions for
12:20 things . Um so when you make , when you're
12:23 taking a measurement of something you can use uh this
12:26 number 20 cm and then as you're taking the next
12:30 measurement it's very common to say bye . So 20
12:33 centimetres by 40 centimeters by 60 centimeters as you're measuring
12:39 something . That's a very common way to express that
12:42 . So I hope that this is helpful for you
12:45 in terms of the measurements of objects . But if
12:48 you have any questions or comments or if there's something
12:51 you would like to practice , if you want to
12:53 make an example measurement for example uh in the comment
12:57 section please feel free to do that as well .
