How volume calculation works
Volume measures the three-dimensional space a solid shape occupies, always expressed in cubic units — in³, ft³, cm³, m³, etc. Each geometric solid has a dedicated formula derived from its properties. This calculator applies the exact formula and shows you the full working, so you understand the result — not just the number.
Frequently asked questions
Sphere volume calculator
Use the sphere volume calculator to find the volume of any sphere. Formula: V = (4/3) × π × r³, where r is the radius. Example: a sphere with radius 3 cm has a volume of 113.10 cm³.
Cube volume calculator
Use the cube volume calculator to find the volume of any cube. Formula: V = s³, where s is the side length. Example: a cube with side 4 ft has a volume of 64 ft³.
Rectangular prism volume calculator
Use the rectangular prism volume calculator to find the volume of any box. Formula: V = l × w × h. Example: 5 × 4 × 3 inches = 60 in³.
Cylinder volume calculator
Use the cylinder volume calculator to find the volume of any cylinder. Formula: V = π × r² × h. Example: radius 3 in, height 10 in → volume = 282.74 in³.
Cone volume calculator
Use the cone volume calculator to find the volume of any cone. Formula: V = (1/3) × π × r² × h. Example: radius 3 in, height 6 in → volume = 56.55 in³.
Pyramid volume calculator
Use the pyramid volume calculator to find the volume of any square pyramid. Formula: V = (1/3) × base² × h. Example: base 4 m, height 9 m → volume = 48 m³.
Triangular prism volume calculator
Use the triangular prism volume calculator. Formula: V = ½ × b × h × l. Example: b = 6, h = 4, l = 10 ft → volume = 120 ft³.
Ellipsoid volume calculator
Use the ellipsoid volume calculator. Formula: V = (4/3) × π × a × b × c. Example: a=3, b=2, c=1 m → volume = 25.13 m³.
