Question

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

Answer 1

Volume of a cube = a³
a³ = 64
a = 4 inches

Surface area of a cube = 6a²
Surface area = 6*4²
= 96 square inches

Answer 2

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
