What Is a Rectangular Prism?

A rectangular prism is a three-dimensional object that has six faces that are all rectangles. On a rectangular prism, opposite faces are both equal and parallel. Rectangular prisms also have the same cross section along their lengths.

A cuboid, which is a three-dimensional object that has six flat sides and all right angles, is a type of rectangular prism. If a prism has at least two lengths that are equal, it is a square prism instead of a rectangular prism. The equation to determine the volume for a rectangular prism is length x width x height. To determine the surface area of a rectangular prism, the equation is 2(lw + wh + lh).
