What shapes does this volume calculator cover?

Commonly cubes, spheres, cylinders, cones, and rectangular boxes.

What does volume measure?

The amount of 3D space an object occupies.

Why do different shapes need different volume formulas?

Each shape's geometry distributes space differently.

What Is a Volume Calculator?

This calculator finds the volume and surface area of the five most common 3D shapes: cube, rectangular box, sphere, cylinder, and cone.

Volume Formulas

Cube: V = s³
Rectangular Box: V = length × width × height
Sphere: V = (4/3)πr³
Cylinder: V = πr²h
Cone: V = (1/3)πr²h

How to Use This Calculator

Select the shape you want to measure.
Fill in the dimensions requested for that shape (only relevant fields appear).
Click Calculate to get the volume and surface area.

Worked Example

A cylindrical water tank has a radius of 4 m and a height of 10 m. Volume = π × 4² × 10 ≈ 502.65 m³. Select "Cylinder" above and enter radius 4 and height 10 to verify.

Common Uses

Volume calculations help estimate material for concrete pours, water tank or aquarium capacity, packaging and shipping box sizes, and any container or 3D object encountered in school, DIY, or engineering work.
