Formulas & reference
Cube: a³Sphere: (4/3)πr³Cylinder: πr²hCone: (1/3)πr²hRectangular prism: lwh
Volume tips
- Cone is one-third of a cylinder with same r,h
- Sphere scales with r³
- Prism is length×width×height
- Keep units consistent
Calculation logic
Dispatches to the selected volume formula using M_PI for round solids.
Cone and cylinder heights are perpendicular heights.
