Volume Calculator – Sphere, Cube, Cylinder

How does the volume calculator work?

This calculator computes the volume of three basic 3D shapes using standard geometric formulas: sphere = (4/3)πr³, cube = s³, and cylinder = πr²h. Select the shape, enter the required dimensions, and click "Calculate". The result appears instantly in cubic units corresponding to the units you used for the input. It's a quick reference for construction, packaging, shipping, or classroom geometry.

How to use the Volume Calculator

Choose a shape from the dropdown — sphere, cube, or cylinder. The input fields automatically adjust to show only what's needed: radius for sphere; side length for cube; radius and height for cylinder. Enter your values and click "Calculate" to see the volume. Switch between shapes anytime.

Example calculations

Sphere r=5 → V = (4/3)π·125 ≈ 523.60 cubic units. Cube s=5 → V = 5³ = 125 cubic units. Cylinder r=5, h=10 → V = π·25·10 ≈ 785.40 cubic units. The calculator delivers precise results for any positive input values.

Frequently Asked Questions

What units does the calculator use?

The calculator works with pure numbers. If you enter dimensions in centimeters, the volume is in cm³; in inches, it's in³; in meters, m³. Always use consistent units for all inputs of a single calculation.

Can I calculate other shapes like a cone or pyramid?

This version covers sphere, cube, and cylinder. For other shapes, you can use our dedicated Shape Area Calculator for 2D areas, or look for a more comprehensive 3D volume tool that includes cones, pyramids, and prisms.
