Answer:
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
