How many cubes with the side length of 1/2 unit do you need to form a three unit cube

216 cubes.

Step-by-step explanation:

The easiest way to take on this problem is to divide the side of the bigger cube by the smaller one.

Then, as in with volume, we cube this value to find the number of cubes necessary to fill such a space.

216

Step-by-step explanation:

Volume of the smaller cube:

(½)³ = ⅛

Volume of the larger cube:

3³ = 27

No. of smaller cubes required:

27 ÷ ⅛

27 × 8

216
