Online Pyramid Frustum Calculator
Calculate the volume of a pyramid frustum (truncated pyramid) from base areas or side lengths and height.
Frequently Asked Questions
- What is a pyramid frustum?
- A pyramid with the top cut off by a plane parallel to the base. You need areas of the two bases (or side lengths for square bases) and height.
- What is the volume formula?
- V = (h/3)(A₁ + A₂ + √(A₁A₂)) where A₁, A₂ are the two base areas and h is height.
- Square bases?
- If bottom side is a and top side is b, then A₁ = a², A₂ = b²; use the same formula.
