Step-by-step calculation
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 = 10 × 5 × 4
Volume = 200 m³
Therefore, the volume of the rectangular prism is 200 cubic meters.
Formula used
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
