## Surface Area of Cube

In general, the surface area is the sum of all the areas of all the shapes that cover the surface of the object.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.
