Volume Calculator

Calculate the volume of cubes, rectangular prisms, cylinders, spheres, and cones with this free volume calculator.

Calculate Volume

Volume = side³ = 5³
Volume = length × width × height = 10 × 6 × 4
Volume = πr²h = π × 3² × 8
Volume = 4/3 × π × r³ = 4/3 × π × 4³
Volume = 1/3 × π × r² × h = 1/3 × π × 3² × 9

How volume is calculated

Cube:
V = s³

Rectangular Prism:
V = l × w × h

Cylinder:
V = πr²h

Cone:
V = 1/3 × πr²h

Why volume matters

Volume is used in geometry, storage, construction, engineering, shipping, and many real-world measurement problems.

It helps estimate capacity, material needs, and container space.

What your result means

Your result shows the volume of the selected solid using the dimensions entered. It also includes the formula and supporting values used in the calculation.

This makes it easier to verify your work and understand how each dimension affects total volume.
