A cube has a volume of 64 cubic units. What is its surface area

Volume of a cube = a³

a³ = 64

a = 4 inches

Surface area of a cube = 6a²

Surface area = 6*4²

= 96 square inches

The volume of a cube is length x width x depth. In a cube all would be equal therefore.

x^3 = 64

x = 4

The area in square feet of one side would then be length x width

There are 6 sides so the surface area of the cube would be

(4) (4) (6) = 96 square feet
