Volume Formulas Explained
| Shape | Formula | Description | Example |
|---|---|---|---|
| Cube | V = a³ | All sides equal length | 4³ = 64 cm³ |
| Rectangular Prism | V = l × w × h | Length × width × height | 5 × 3 × 2 = 30 cm³ |
| Cylinder | V = π × r² × h | Circular base × height | π × 3² × 5 ≈ 141.3 cm³ |
| Sphere | V = (4/3) × π × r³ | Perfectly round object | (4/3) × π × 3³ ≈ 113.1 cm³ |
| Cone | V = (1/3) × π × r² × h | Circular base, tapers to point | (1/3) × π × 3² × 5 ≈ 47.1 cm³ |
| Pyramid | V = (1/3) × base area × h | Base and triangular sides | (1/3) × 25 × 6 = 50 cm³ |

📐 Volume Formulas for Common Shapes
1. Cube
Formula: Volume = a³
Where: a = side length
Example: If side = 4 cm, Volume = 4 × 4 × 4 = 64 cm³
2. Rectangular Prism (Box)
Formula: Volume = length × width × height
Example: Length = 5, Width = 3, Height = 2, Volume = 5 × 3 × 2 = 30 cm³
3. Cylinder
Formula: Volume = π × r² × h
Where: r = radius, h = height
Example: Radius = 3, Height = 5, Volume ≈ 3.14 × 9 × 5 = 141.3 cm³
