Best ResponseYou've already chosen the best response.1set \[x^2+4xh=1200\] and solve for\(h\)

Best ResponseYou've already chosen the best response.1i get \[h=\frac{1200x^2}{x}\]

Best ResponseYou've already chosen the best response.1volume is \[V=x^2h\] or now \[V(x)=x^2\left(\frac{1200x^2}{4x}\right)\]or \[V(x)=\frac{1}{4}x(1200x^2)\]

Best ResponseYou've already chosen the best response.1the derivative is a lot simpler than that, it is just \[V'(x)=300\frac{3}{4}x^2\]
