Volume Formulas

Cube: V = s³ Box: V = l × w × h Cylinder: V = π × r² × h Sphere: V = (4/3) × π × r³ Cone: V = (1/3) × π × r² × h Sq Pyramid: V = (1/3) × base² × h Capsule: V = π × r² × (4r/3 + h) Ellipsoid: V = (4/3) × π × a × b × c

Frequently Asked Questions

What units are used for volume?+
Volume is expressed in cubic units — the cube of whatever length unit you use. Enter dimensions in feet → get cubic feet (ft³). Enter in meters → get cubic meters (m³). Common conversions: 1 cubic foot = 7.48 gallons; 1 cubic meter = 1000 liters.
How do I find the volume of an irregular shape?+
For irregular shapes, use water displacement: submerge the object in water and measure how much the water level rises. Volume = rise in water level × container base area. This is Archimedes' principle.
