| A cube is a parallelepiped with all faces the same. There are six faces, the area of each is equal to a ^ 2, where a is the side of the cube. The surface area of the cube is S = 6a ^ 2.
We know that the surface area of a cube is 96 cm2, which means 6a ^ 2 = 96, from here we find a:
a ^ 2 = 96: 6 = 16,
a = 4.
The volume of the cube is V = a ^ 3 = 4 ^ 3 = 64 cm3.
