Pyramid Volume Calculator
Calculate the volume of a pyramid from its base dimensions and height. Supports square and rectangular base pyramids.
Enter base dimensions and height.
Pyramid Volume Formula
Volume = ⅓ × Base Area × Height
For rectangular base: V = ⅓ × l × w × h
For rectangular base: V = ⅓ × l × w × h
Example: Square base (side = 5), height = 9.
V = ⅓ × 5 × 5 × 9 = ⅓ × 225 = 75 cubic units
V = ⅓ × 5 × 5 × 9 = ⅓ × 225 = 75 cubic units
FAQ
What is the relationship between a pyramid and a prism?
A pyramid's volume is exactly ⅓ of a prism (box) with the same base and height, similar to how a cone's volume is ⅓ of a cylinder.
What about triangular pyramids?
For a triangular base pyramid (tetrahedron), first calculate the triangle's area, then multiply by height and divide by 3.
