How to use this calculator

  1. Choose L×W×H or base-area mode.
  2. Enter the visible fields.
  3. Read volume.
  4. Keep all lengths in the same unit.

Results explained

Any pyramid (or cone) volume is one-third base area times height. For a rectangular base, base area = length × width.

Quick reference: pyramid volume

V = (1/3) × B × h.

vs prismPyramid is 1/3
UnitsCubic units of the inputs

Oblique pyramids still use perpendicular height.

How the estimate is built

V = (1/3)×length×width×height or (1/3)×baseArea×height.

Example scenario

6×6 base, height 10 → 120.
