The total surface area of a prism is the sum of the areas of its lateral faces and its two bases, which is not so different from the cube or box. A cube is a prism having six square faces (both lateral faces and bases), thus its surface area is the sum of the areas of its six square faces. A box is a prism having 3 pairs of congruent faces, namely two pairs of its lateral faces and its bases; thus, its surface area is twice the sum of the areas of the three faces with their congruent pair. Learn how to calculate surface area of a prism, cube, and box by helping Sam Serpentino, an aspiring movie director, keeps his movie map just right in order to impress the studio executive for his new movie idea, “Attack of the Really Really Big Slugs from Outer Space” .
