In this module, you can study how to find the surface area of a cube, a cuboid (or rectangular prism) and a triangular prism.
The surface area formulae for all prisms and cylinders are the same. They are all (two x the area of the base) plus (the perimeter of the base x the height of the object).
Even though a prism is a three-dimensional object, its surface area is two-dimensional.
