Best ResponseYou've already chosen the best response.0Because then you don't have to find the surface areas of more faces  you can just find the surface area of one side and then multiply that amount by the number of congruent sides. For example, a cube that is 10 inches x 10 inches x 10 inches has six congruent faces, each 10"x10". Therefore, one side =10x10=100in sq. Now just multiply 100x6 =600 sq in. for the whole box. If the faces were all different, I would have to find the surface area of each face separately and then add them all together.
