I don't trust the formula as given, for several reasons.

First, it looks as if you omitted some essential parentheses, e.g. around "b-d".

But more important, the volume should be proportional to h, and this is not apparent as I would expect in any reasonably derived formula.

But if the formula is correct, then the answer would be found by "just" solving for h. Try factoring out h!

Thank you for pointing this out... yes the b-d should be in parenthesis on both instances...

That's the thing I'm having trouble with is factoring out the h.. I have tried several ways but I get stuck in a loop of passing the "h" back and forth from the equal sign.

I start with this: 3V/pi=(ab)(bh/(b-d))-(cd)(bh/(b-d))-h).. but kinda lost after that.
