The unit of measurement for the surface area of rectangular prism is done in square units. The area of the right face is also 20 square inches. When you have a cube, finding the area of one face allows you to find the total surface area of the solid very quickly, since it will be six times the area of one face. The surface area of the rectangular prism is the sum of the area of lateral faces and rectangular bases. Let’s start with the side that stares you in the face on the diagram. The surface area of a rectangular prism is the total area of all six faces.This box has six sides, three pairs of congruent sides. The area of each side is length times width.
