Purpose of use

calculate filling volume of hopper

Comment/Request

would be really nice to have a formula to calculate a volume at a height within the obelisk/parazoid. so if you want to have an intermediate level, where you don't know the exact top/base dimensions from, where you only know this of the complete hopper

I the formula proved / derived.

I use the formula: V = h/4 x ( A-a) x (B-b)+ h/12 x (A-a) x (B-b)

These formula give the same result, and is easy to understand.

Purpose of use

Determine the volume of a sand house needed to contain 2,000 tons of cinders.

Comment/Request

It would be handy if one could input the angle of repose to determine a and b given h, A, B and the angle of repose. Very helpful website. Thanks
