Frequently Asked Questions

What shapes can I calculate volume for?

The calculator supports 8 common 3D shapes: cube, rectangular prism (box), sphere, cylinder, cone, pyramid (rectangular base), ellipsoid, and hemisphere. Each shape has its own set of required input dimensions.

What units of measurement are available?

You can use millimeters (mm), centimeters (cm), meters (m), inches (in), feet (ft), or yards (yd). The volume result will be in the cubic form of the selected unit (e.g., cm³, m³, ft³).

How accurate are the calculations?

The calculator uses standard mathematical formulas with up to 6 decimal places of precision. For shapes involving π (pi), the full JavaScript Math.PI constant (approximately 3.141592653589793) is used.

What is the formula for a sphere's volume?

The volume of a sphere is V = (4/3)πr³, where r is the radius. For example, a sphere with a 5 cm radius has a volume of approximately 523.60 cm³.

Is my data private?

Yes. All calculations run in your browser using JavaScript. No data is sent to any server. Your inputs and results remain completely private.

Pro Tips

  • Double-check units before calculating to avoid errors
  • Use the rectangular prism for box-shaped containers
  • For irregular shapes, try approximating with an ellipsoid
  • Copy the result to paste into reports or assignments
