Volume Calculator accuracy and testing

Formula source

• Different shapes use specific formulas based on their dimensions: * **Cylinder:** $\pi \times r^2 \times h$ (Area of base × Height) * **Sphere:** $\frac{4}{3} \times \pi \times r^3$ * **Cone:** $\frac{1}{3} \times \pi \times r^2 \times h$ * **Cube:** $side^3$ * **Rectangular Prism:** $Length \times Width \times Height$

Test cases

Known limitations

• This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
• Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

• All dimensions are entered in the same linear unit, and the result is returned in cubic units.
• Dimensions are treated as non-negative geometric lengths.
• This calculator returns geometric volume only and does not convert capacity into weight without a separate density value.

Unit handling

• Shape accepts one of the configured options.
• Radius (r) accepts numeric values.
• Height (h) accepts numeric values.
• Width (w) accepts numeric values.
• Length (l/side) accepts numeric values.

Rounding rules

• Number displays use up to 2 decimal places in the calculator UI.
