The rectangular prism also has six faces, or flat sides. The surface area of a rectangular prism is determined by multiplying the length by the width of each of the six rectangles and by then adding the products together. Finding the area of one of each of the parallel faces, multiplying by two and adding those products together gives the same answer. The volume of the rectangular prism is determined by multiplying the length times the width times the height of the prism.

The surface area of a rectangular prism is the combined surface areas of all six of its sides. Because opposing sides are always the same size, the total surface can be determined by using the length, width and height of the front, top and side of the prism.
