## Homework Equations

## The Attempt at a Solution

I'm usually fairly decent at optimization questions. Is this solvable with the given information? It seems to me to be missing something because no values or relationships are ever assigned to weight. I don't even know where to start; I can easily set up an equation for volume, but I also need to find an equation for weight. If you think it's solvable, please do not give me the solution. Just nudge me in the correct direction. :)
