- Enter the base length, width and height.
- Press Calculate.
How it works
Volume = (length × width × height) ÷ 3 — a third of the box around it.
Worked example
3 × 3 × 4 m. = 12 m³.
Common mistakes
- Forgetting the one-third factor — a pyramid holds a third of the prism around it.
- Using slant height instead of vertical height for the volume.
Frequently asked questions
How do I calculate the volume of a pyramid?
Volume = (1/3) × base area × vertical height. The base can be any shape; just use its area.
Why the one-third factor?
A pyramid fills exactly one-third of the prism with the same base and height, which is where the 1/3 comes from.
Why divide by 3?
A pyramid holds exactly one third of the box (prism) with the same base and height — that's the ÷ 3 in the formula.
