A cube has a volume of 27 cubic inches. What's its surface area?

54 square inches

Explanation

Volume is calculated by multiplying length times width times height (V = lwh). Because the edges are equal on a cube, each edge is 3 inches. The cube root of 27 produces this number: 64 = 3 * 3 *3. The area of one side of the cube is 3 * 3 = 9 and because a cube has 6 sides you multiply 9 * 6 to find the surface area of the cube = 54 square inches.
