lets call the height $h$ then $$x^2+4xh=A$$ solve that for $h$

anonymous · Answer

the volume will be $$V=x^2h$$ once you have solved $x^2+4xh=A$ for $h$ you can substitute it back in to the formula for the volume

akathuria19 · Answer

I get h = ((A/x)-x)/4

Then plugged in it looks like: 

V = x^2((A/x)-x)/4)
