About Volume Calculator

The Volume Calculator helps you calculate the volume of various 3D geometric shapes using their specific formulas.

Supported Shapes:

  • Cube: Volume = side³
  • Rectangular Prism: Volume = length × width × height
  • Cylinder: Volume = π × radius² × height
  • Sphere: Volume = (4/3) × π × radius³
  • Cone: Volume = (1/3) × π × radius² × height
  • Pyramid: Volume = (1/3) × length × width × height

Applications:

  • Construction and architecture
  • Manufacturing and engineering
  • Packaging and shipping
  • Mathematics education
  • Scientific research
  • Interior design

Units:

  • Volume is measured in cubic units
  • Common units: cubic meters, cubic feet, cubic inches
  • Liquid volume: liters, gallons, milliliters
  • Use consistent units for all measurements

Important Notes:

  • All measurements should be in the same units
  • Results are rounded to 2 decimal places
  • For irregular shapes, use approximation methods
  • Consider significant figures in scientific calculations

Note: This calculator provides estimates for regular geometric shapes. For complex or irregular shapes, consider using numerical integration or specialized software.

Frequently Asked Questions

How do I calculate the volume of a cube?

To calculate the volume of a cube, cube the length of one side. Formula: Volume = side³.

What's the formula for cylinder volume?

The volume of a cylinder is calculated using: Volume = π × radius² × height.

How do I find the volume of a sphere?

The volume of a sphere is calculated using: Volume = (4/3) × π × radius³.

What's the difference between volume and area?

Volume measures the space inside a 3D shape (in cubic units), while area measures the surface of a 2D shape (in square units).

Can I calculate volume in different units?

Yes, you can use any unit of measurement (meters, feet, inches, etc.). Just make sure all measurements use the same unit, and the result will be in cubic units.
