# The length of the

Given: Length of the diagonal of a cube is 6 √ 3 cm.

We know that the Length of a diagonal of a cube is given by: a√ 3 (here ‘a’ is edge length of cube)

a 3 = 6 3

a = 6cm

Edge length of the cube is 6cm.

Surface area of a cube is given by: 6a2 (here ‘a’ is the edge length)

Let ‘S’ be the surface area of the given Cube.

S = 6a2

S = 6 × (6)2

S = 216 cm2

Surface area of the given cube is 216 cm2
