Name the ideal solid
Choose the geometry matching the space before entering numbers.
Eight solids · exact cubic factors
Calculate the three-dimensional space the formula actually describes.
VolumeCalc pairs each ideal solid with the dimensions it needs, cubes unit factors exactly, and separates symbolic π from its decimal approximation. Measurements stay in the browser.
No account, upload, camera, CAD, material estimate, real-capacity claim, or generated result URL.
Three visible choices
Match the solid, dimensions, and cubic unit
Measure the required dimensions
Distinguish radius from diameter, semiaxes from axes, and perpendicular height from slant height.
Cube the unit conversion
VolumeCalc converts through exact cubic-metre factors and exact litre relationships.
Eight focused formulas
Common ideal solids without physical assumptions
- Rectangular prism and cube.
- Cylinder, cone, and sphere with exact π coefficients.
- Triangular prism and square pyramid from perpendicular height.
- Ellipsoid from three semiaxes; cubic units, mL, and L output.
Choose, measure, verify
Turn three-dimensional measurements into a volume you can check
Match the ideal solid, keep dimensions in one length unit, and inspect the substituted formula before using a converted result.
