If it is the frustum of a pyramid: The volume of a pyramid (with a square base) is: Length_of_base * Width_of_base * Height * 1/3 To get the volume of the frustum, subtract the volume of the top part (also a pyramid) from the full volume.

frustum of a cone

the formula is

(h*pi)/3*(r1^2+r2^2+r1*r2)

this is where h = height r1= top radius r2=bottom radius

How do you calculate weight of frustum?

To calculate the weight of a frustum, first determine its volume using the formula: ( V = \frac{1}{3} \pi h (R^2 + r^2 + Rr) ), where ( R ) is the radius of the larger base, ( r ) is the radius of the smaller base, and ( h ) is the height. Once you have the volume, multiply it by the material's density (( \text{Weight} = \text{Volume} \times \text{Density} )) to find the weight of the frustum.
