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.
the area of the rectangle is the circumference of the circle x height or (2 r) * h. Add those two parts together and you have the formula for the surface area of a cylinder.
Cuboids, Rectangular Prisms and Cubes. It has six flat faces and all angles are right angles. It is also a prism because it has the same cross-section along a length. In fact it is a rectangular prism
In a rectangular cuboid, all angles are right angles, and opposite faces of a cuboid are equal. By definition this makes it a right rectangular prism, and the terms rectangular parallelepiped or orthogonal parallelepiped are also used to designate this polyhedron.
