hi,
what "non geometric" is ?

Not a rectangle but is it a plane figure ?

Is it a spatial surface ? Is it a closed volume ?

What data have you ?

bye

I remember from calculus that you calculate it in terms of super small squares filling it. But I forget what to do exactly.

I think you run functions going to 0 or something.

you integrate from left to right the area of the cross-section perpenducular to the base of the shape.
