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:
A) x^2  B) x^3  C) x^6  D) 6x^2  E) 6x^3
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*x2   Correct Option: 6x^2
