I need help with this project. see http://imgur.com/DCKOP I specifically need help with the first two parts, the last two I can figure out on my own for sure. I've already figured out the restraint equation girth + longest dimension 0 But I'm not sure what to do for payoff function or other parts.

I specifically need help with the first two parts, the last two I can figure out on my own for sure.

I've already figured out the restraint equation 

girth + longest dimension <= 180 inches
height - diameter > 0

But I'm not sure what to do for payoff function or other parts.

Well it says that the payoff function is volume, so I would probably start with dimensions.|dw:1335060612432:dw|
You know that volume equals area times length, so s^2* L.
