What the volume calculator solves
Use the volume calculator to find how much three-dimensional space a solid occupies.
Formula
How to use it
- Choose the solid.
- Enter the dimensions shown.
- Read the volume and the formula used.
How to read the answer
Volume is measured in cubic units because it combines three dimensions.
Common mistakes and edge cases
- Keep every length in the same unit.
- Use radius for round solids, not diameter.
- Cones have one third of the matching cylinder volume.

Frequently asked questions
What is the difference between area and volume?+
Area covers a flat surface in square units. Volume fills a 3D solid in cubic units.
Can this calculate liquid capacity?+
Yes, if your dimensions are in compatible units. You may then convert cubic units to liters or gallons with a volume converter.
