If the volume of a cube is 729cm3, what is the surface area of the cube?

486

Step-by-step explanation:

Volume of Cube = a^3

Surface area of Cube = 6a^2

Given that the Volume of the cube is equals 729cm^3, a^3 = 729cm3

Taking the cube roots of both sides, we have

(a3) ^1/3 = cube root of (729)

a = 9.

Similarly, Surafce area of cube is 6a^2, but a = 9.

Therefore, Surface area = 6 (9) ^2 = 486cm2

The correct answer is 486cm^3
