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.
