If the volume of a cube is x^3 cubic units, what is the number of square units in the surface area of the cube?	Choose the correct choice from the following answers
A) x ^ 2	B) x ^ 3	C) x ^ 6	D) 6 x ^ 2	E) 6 x ^ 3

Rationale: the question basically asks you to calculate the surface area of the cube . volume of the cube = x ^ 3 this means each side of the cube = x hence area of each side = x ^ 2 total surfaces in a cube = 6 total surface area = 6 * x 2 correct option : d
Answer: D
