Volume Calculator
Volume and surface area for cubes, cylinders, spheres and cones.
What is a volume calculator?
A volume calculator finds the volume and surface area of a shape. Choose a cube, cylinder, sphere or cone, enter its measurements, and the calculator does the rest.
How to use the volume calculator
Pick the shape, enter the radius or side and the height where needed, then click Calculate. The volume and surface area appear with the steps.
Volume formulas
Cylinder: V = π × r² × h. Cube: V = side³. Sphere: V = 4/3 × π × r³. Cone: V = 1/3 × π × r² × h.
Example
A cylinder with radius 3 and height 5 has volume V = π × 3² × 5 = 141.37, and its surface area is 150.79645.
