Best answer
Correct Answer - Option 1 : 216

Given:

The edge length of cube = 3 cm

Formula used:

Volume of cube = (side)3

Calculation:

Let the number of cubes that can be cut from bigger cube be N

And we know that,

N × Volume of smaller cube = Volume of bigger cube

⇒ N × (3)3 = (18)3

⇒ N = (18)3/(3)3

⇒ N = 216

∴ Number of cubes that can be cut from bigger cube is 216.
