What is volume?

Volume is the amount of three-dimensional space occupied by an object. It is measured in cubic units, such as cubic meters, cubic centimeters, or cubic feet.

Different three-dimensional shapes use different formulas to calculate their volume.

How is volume calculated?

The volume formula depends on the shape being measured. For example, the volume of a rectangular prism is found by multiplying its length, width, and height.

For curved shapes such as cylinders, spheres, and cones, formulas involving π are used. The calculator selects the appropriate formula based on the shape you choose.

Volume calculator example

Suppose you have a rectangular prism that is 10 meters long, 5 meters wide, and 4 meters high.

Volume = Length × Width × Height

Volume = 10 × 5 × 4

Volume = 200 m³

Therefore, the volume of the rectangular prism is 200 cubic meters.

Formula used

Rectangular Prism:
Volume = Length × Width × Height

Cube:
Volume = Side³

Cylinder:
Volume = π × Radius² × Height

Sphere:
Volume = ⁴⁄₃ × π × Radius³

Cone:
Volume = ¹⁄₃ × π × Radius² × Height

Triangular Prism:
Volume = ½ × Base × Triangle Height × Prism Length
