Question

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

Answer 1

Answer:

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

Answer 2

Answer:

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.

$3 \div \frac{1}{2} = 3 \times 2 = 6$

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

${6}^{3} = 216$
