Volume Formulas for 3D Shapes
Understanding the mathematical formulas behind volume calculations helps in learning geometry and verifying results. Here are the formulas used by our calculator:
Cube Volume Formula
Formula: V = s³
Where s is the side length of the cube. Since all sides of a cube are equal, you only need to measure one side and cube it (multiply by itself three times).
Example: A cube with 5 cm sides has a volume of 5³ = 5 × 5 × 5 = 125 cm³
Rectangular Prism Volume Formula
Formula: V = l × w × h
Where l is length, w is width, and h is height. This is the most straightforward volume calculation, simply multiplying the three dimensions.
Example: A box measuring 10 × 8 × 6 cm has a volume of 480 cm³
Cylinder Volume Formula
Formula: V = π × r² × h
Where r is the radius of the circular base and h is the height. The formula calculates the area of the circular base (π × r²) and multiplies by height.
Example: A cylinder with radius 3 cm and height 10 cm has a volume of π × 3² × 10 = 282.74 cm³
Sphere Volume Formula
Formula: V = (4/3) × π × r³
Where r is the radius of the sphere. This formula derives from calculus and represents the volume of a perfectly round object.
Example: A sphere with radius 4 cm has a volume of (4/3) × π × 4³ = 268.08 cm³
Cone Volume Formula
Formula: V = (1/3) × π × r² × h
Where r is the radius of the circular base and h is the height from base to apex. The volume is one-third of a cylinder with the same base and height.
Example: A cone with radius 3 cm and height 8 cm has a volume of (1/3) × π × 3² × 8 = 75.40 cm³
Pyramid Volume Formula
Formula: V = (1/3) × l × w × h
Where l is base length, w is base width, and h is height from base to apex. For square pyramids, length equals width.
Example: A pyramid with 6 × 6 cm base and 9 cm height has a volume of (1/3) × 6 × 6 × 9 = 108 cm³
Unit Conversions for Volume
Our calculator automatically converts between different volume units to help you work with measurements in your preferred system:
Metric Volume Units
- Cubic Centimeters (cm³): Base metric unit for small volumes
- Cubic Meters (m³): Standard metric unit for large volumes
- Liters (L): Common unit for liquid volumes (1 L = 1000 cm³)
- Milliliters (mL): Small liquid volumes (1 mL = 1 cm³)
Imperial Volume Units
- Cubic Inches (in³): Base imperial unit for small volumes
- Cubic Feet (ft³): Standard imperial unit for large volumes
- Gallons (gal): Common unit for liquid volumes
- Fluid Ounces (fl oz): Small liquid volumes
Conversion Factors
Key conversion factors used in our calculator:
- 1 m³ = 1,000,000 cm³
- 1 ft³ = 1,728 in³
- 1 m³ = 35.314 ft³
- 1 L = 1,000 cm³ = 0.264 gallons
- 1 gallon = 3,785.41 cm³ = 231 in³
