Because nothing mathematical is ever created by mere humans, only discovered,
I believe Mathematics to be the language of God.  And as such, there is a
unique function which describes your shell.  All you have to do is find that
function and apply a triple integration to it.  Simple, isn't it?  Sure!  You
can APPROXIMATE it by considering the form to be that of a cylinder capped by
two appropriate sections of a sphere.  Using that approach assumes that the
end caps were accurately formed into spherical sections to begin with and it
ignores the radiused corners where the caps join the cylinder.  So, you
venture farther into the realm of assumption and approximation.  I would
rather take the advice of a wise man and measure how much water it holds.
Probably, the next topic should be how to desiccate a wet LP tank.
