(adsbygoogle = window.adsbygoogle || []).push({}); Minimizing Construction Costs: If an open box has a square base and a volume of 108 in.^3, and is constructed from a tin sheet, find the dimensions of the box, assuming a minimum amount of material is used in its construction.

This is what I have so far:

[tex]Volume: 4y^3-4xy^2+x^2y=1=108[/tex]

[tex]x=-\sqrt{\frac{108}{y}}+2y[/tex]

Now I'm not sure if these are right so, please feel free to correct me. I would much appreciate it!
