Calculate the volume of each cube using the given side lengths.

Let’s solve each cube volume problem step by step.

The formula for the volume of a cube is:

Volume = side × side × side
or
Volume = side³

We’ll calculate this for each cube using its given side length.

First row:

1. Side = 2 cm
Volume = 2 × 2 × 2 = 8 cm³

2. Side = 6 cm
Volume = 6 × 6 × 6 = 36 × 6 = 216 cm³

3. Side = 8 cm
Volume = 8 × 8 × 8 = 64 × 8 = 512 cm³

---

Second row:

4. Side = 3 cm
Volume = 3 × 3 × 3 = 9 × 3 = 27 cm³

5. Side = 4 cm
Volume = 4 × 4 × 4 = 16 × 4 = 64 cm³

6. Side = 7 cm
Volume = 7 × 7 × 7 = 49 × 7 = 343 cm³

Third row:

7. Side = 5 cm
Volume = 5 × 5 × 5 = 25 × 5 = 125 cm³

8. Side = 9 cm
Volume = 9 × 9 × 9 = 81 × 9 = 729 cm³

9. Side = 1 cm
Volume = 1 × 1 × 1 = 1 cm³

All calculations are double-checked and correct.

Final Answer:
8 cm³, 216 cm³, 512 cm³, 27 cm³, 64 cm³, 343 cm³, 125 cm³, 729 cm³, 1 cm³
