Question: what is surface area of cubes and prisms?
Answer: In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared. Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac.
