Question

If a cube has a volume of 64, what is its total surface area? A) 16

Answer 1

Volume of cube = (length of an edge)³

Let the length of an edge of a cube be "a" unit.

Then, a³ = 64

Or, a = 4 unit

Total surface area of a cube is given by the formula of 6 a² which is actually equal to 6×(4)² unit = 96 unit
