Step-by-step

  1. Base area = a² = 6² = 36.0000.
  2. V = (1/3) × base × height = (1/3) × 36.0000 × 8 = 96.0000.

How to use this calculator

  • Pick base shape.
  • Enter base dimensions and pyramid height (perpendicular).
  • Read volume.

About this calculator

A pyramid has a polygonal base and triangular faces meeting at an apex. Volume = (1/3) × base area × height. The (1/3) factor is the same as for cones (Cavalieri's principle). Examples: square base = traditional Egyptian pyramid; triangular base = tetrahedron variant. The Great Pyramid of Giza has ~230 m sides × 147 m height → ~2.6 million m³.

Frequently asked

Same reason as cones: a pyramid on the same base and height has 1/3 the volume of the corresponding prism. Geometric proof via Cavalieri.
