# The total surface

Answer :

Given: The total surface area of a cube is 864 cm2.

We know that the Volume of a cube is given by: 6a2 (here ‘a’ is edge length of cube)

6a2 = 864

a2 = = 144

a = 144

a =12cm

Edge length of the cube is 12cm.

Volume of a cube is given by: a3 (here ‘a’ is the edge length)

Let ‘V’ be the Volume of the given Cube.

V = a3

V = (12)3

V = 1728 cm3

Volume of the given cube is 1728 cm3
