What is Volume?
Volume measures the amount of three-dimensional space occupied by an object or contained within a boundary. It is expressed in cubic units such as cubic meters (m³), cubic centimeters (cm³), liters (L), or cubic feet (ft³). Calculating volume is essential in mathematics, engineering, architecture, manufacturing, and many practical applications.
How to Calculate Volume
- Choose the geometric shape you want to calculate.
- Enter the specific dimensions for your selected shape.
- Select your preferred unit of measurement.
- Click the "Calculate Volume" button to get your result.
- Copy the result or use the clear button to reset the calculator.
Example – Cube:
Side length: 5 meters
Result: 125 cubic meters (m³)
Formula: Volume = side³ = 5³ = 125 m³
Supported Shapes and Volume Formulas
- Cube: Volume = side³
- Sphere: Volume = (4/3) × π × radius³
- Cylinder: Volume = π × radius² × height
- Cone: Volume = (1/3) × π × radius² × height
- Rectangular Prism: Volume = length × width × height
- Pyramid: Volume = (1/3) × base area × height
Frequently Asked Questions (FAQ)
Volume is the measure of space an object occupies, while capacity indicates how much a container can hold, typically in liquid or gas form. Volume is measured in cubic units, and capacity is commonly measured in liters, gallons, or similar units. Both concepts are closely related and can often be converted between each other.
This calculator provides formulas for standard geometric shapes. For irregular objects, use methods such as water displacement, 3D modeling, or dividing the object into simpler shapes and calculating each part separately.
The results are based on precise mathematical formulas. The final accuracy depends on the precision of your input values. For calculations involving π (pi), the calculator uses JavaScript's Math.PI, which is accurate for most practical purposes.
Supported units include cubic meters (m³), cubic centimeters (cm³), cubic feet (ft³), cubic inches (in³), liters (L), and gallons (gal). Select your preferred unit from the dropdown menu to display the result accordingly.
