How it works
Cuboid = lwh; cube = side³; cylinder = πr²h; sphere = 4πr³ ÷ 3.
Assumptions and limits
Dimensions use one consistent unit; real tanks, walls, voids, fill limits, and manufacturing tolerances are excluded.
About this calculator
The calculator switches the visible fields and formula with the selected solid to reduce unit and shape errors.
What this tool helps you check
Calculate common solid volume and expose every dimension and unit assumption.
How to use it
- Review the formula and assumptions shown for this volume calculator.
- Choose the solid and enter every dimension in the same unit.
- Calculate and review the cubic result and litre equivalent where available.
- Apply safety capacity, voids, tolerances, and professional measurements separately.
