How it is calculated
The height is dropped perpendicular to the base. The slant height and a lateral edge are other lengths.
V = a² × h / 3
Where the numbers come from
- Base side
- Height
Example
A base side of 3 and a height of 4 give a volume of 3 × 3 × 4 / 3 = 12.
Questions
The base is not a square?
Then work out its area first, and multiply by the height and by 1/3 yourself.
A tetrahedron?
A regular tetrahedron has a triangular base, so this formula does not fit it.
A frustum of a pyramid?
There is a separate calculator for that.
