SammyS, it makes sense that I got the minimum :) (thanks for mentioning it though because I initially thought I was doing something redundant rather than getting a minimum). What you said sounds like what I did though. Could you please be a bit more descriptive algorithmically?

[itex]\displaystyle V=\ell hw[/itex]
If h = w , then
ℓ = 250  4h ,
and [itex]\displaystyle V=(250  4h)h^2\,.[/itex]
Maximize that.
