Sixth grade - Volume and surface area of triangular prisms

A triangular prism has 5 faces, 3 being rectangular and 2 being triangular. The area of the rectangular faces can be found by multiply the base and height lengths together. The area of the triangular faces can be found by multiplying the base and height and dividing by 2.

  • How do you find the base area of a triangular prism?
  • First, substitute the given values into the formula. Then, multiply the sum of the triangle sides by the height of the prism (H) and add the values together for the answer, making sure to include the appropriate unit of measurement. The answer is the surface area of the above triangular prism is 486 square inches.

  • How do you measure the surface area of a triangle?/li>
  • To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

  • How do you find the surface area of a prism?
  • How to find the surface area of Rectangular Prisms:
    Find the area of two sides (Length*Height)*2 sides.
    Find the area of adjacent sides (Width*Height)*2 sides.
    Find the area of ends (Length*Width)*2 ends.
    Add the three areas together to find the surface area.

  • How do you find the volume of a prism and a cylinder?
  • To find the volume of a prism (it doesn’t matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h. A cylinder is a tube and is composed of two parallel congruent circles and a rectangle which base is the circumference of the circle.
