Question

Calculate the volume and surface area of a cube:

Calculate the volume and surface area of a cube with a = 3".  Be sure to involved units in your answer.

Solution:

V = a³                                     SA = 6a²

V = (3)(3)(3)                           SA  = 6(3)(3)

V = 27 cubic inches                SA = 6(9)

SA = 54 square inches
