**Question:**

If the length of the diagonal of a cube is 6√3 cm, then the length of the edge of the cube is 3 cm.

**Solution:**

False

Given, the length of the diagonal of a cube = 6√3 cm

Let the edge (side) of a cube be a cm.

Then, diagonal of a cube =a√3

=> 6√3 = a√3

=> a = 6 cm

Hence, the edge of a cube is 6 cm.
