Volume Calculator
How It Works
This volume calculator uses established formulas to provide accurate results.
The basic rule:
- Cube: V = s³
- Rectangular Prism: V = l × w × h
- Cylinder: V = πr²h
- Cone: V = ⅓πr²h
- Sphere: V = ⁴⁄₃πr³

Frequently Asked Questions
What is volume?
Volume is the amount of three-dimensional space inside a solid shape, measured in cubic units. It tells you how much something can hold.
How do you find the volume of a rectangular prism?
Multiply length × width × height. For example, a box that is 5 × 4 × 3 has a volume of 60 cubic units.
Why is the volume of a cone one-third the volume of a cylinder?
A cone with the same radius and height as a cylinder contains exactly one-third the space. You can demonstrate this by filling a cone with water and pouring it into a matching cylinder — it takes exactly 3 cones to fill the cylinder.
What units are used for volume?
Volume is measured in cubic units: cubic inches (in³), cubic feet (ft³), cubic centimeters (cm³), cubic meters (m³), or liters (1 L = 1,000 cm³).
