Frequently Asked Questions
What is a frustum?
A frustum is the portion of a solid (usually a cone or pyramid) that lies between two parallel planes cutting it. Think of it as a cone or pyramid with the top cut off.
How do you calculate the volume of a frustum?
For a cone frustum: V = (pi*h/3)*(R^2 + R*r + r^2). For a pyramid frustum: V = (h/3)*(A1 + A2 + sqrt(A1*A2)).
