Let's solve the
volume of cubes problem step by step.
---
🔷 Volume of a Cube Formula:
The volume $ V $ of a cube is calculated using the formula:
$$
V = s^3
$$
Where:
- $ s $ = length of one side of the cube
---
We’ll solve each cube one by one.
---
1. Cube with side = 5 m
Formula:
$$
V = s^3 = 5^3
$$
$$
= 5 \times 5 \times 5 = 125
$$
✔ Answer: $ 125 \text{ m}^3 $
---
2. Cube with side = 11 cm
Formula:
$$
V = s^3 = 11^3
$$
$$
= 11 \times 11 \times 11 = 1331
$$
✔ Answer: $ 1331 \text{ cm}^3 $
---
3. Cube with side = 7 cm
Formula:
$$
V = s^3 = 7^3
$$
$$
= 7 \times 7 \times 7 = 343
$$
✔ Answer: $ 343 \text{ cm}^3 $
---
4. Cube with side = 15 mm
Formula:
$$
V = s^3 = 15^3
$$
$$
= 15 \times 15 \times 15 = 3375
$$
✔ Answer: $ 3375 \text{ mm}^3 $
---
✔ Final Answers:
| Number | Side Length | Volume Formula | Volume |
|--------|-------------|-----------------------|--------------------|
| 1 | 5 m | $ 5^3 = 125 $ | $ 125 \text{ m}^3 $ |
| 2 | 11 cm | $ 11^3 = 1331 $ | $ 1331 \text{ cm}^3 $ |
| 3 | 7 cm | $ 7^3 = 343 $ | $ 343 \text{ cm}^3 $ |
| 4 | 15 mm | $ 15^3 = 3375 $ | $ 3375 \text{ mm}^3 $ |

📝 How to Fill in the Worksheet:
For each cube, write:
Formula: $ s^3 $
$ = $ (side) × (side) × (side)
$ = $ (final answer)
Example for #1:
```
Formula: 5³
= 5 × 5 × 5
= 125 m³
```
Repeat similarly for the others.
