Small Cubes
Thanks Jean B

How many small cubes are needed to build this figure?

Find the number of small cubes

Answer: 111 cubes

We start with the right‑side face, which has 21 cubes
That face appears 4 times, giving 21 × 4 = 84 cubes.

Between each of those faces, there are 9 cubes, and there are 3 gaps, so 9 × 3 = 27 cubes.

Add them together: 84 + 27 = 111 cubes.
