luggage problem

I’m a dork, and I want to figure out the optimum dimensions for a piece of luggage I can check on an airplane. The airline I’m flying on says I can have a maximum total length, width, and height of 62 inches. What would be the dimensions that would yield the maximum volume?

FYI, this is not a homework problem, this is for real life applications. I could do the calculus myself, but I’m a little rusty and it would be a struggle. I’m hoping some math genius has some free time on hand.

what is the maximum luggage that a person can carry without paying extra?

Ganesh and Shankar travel abroad and take more luggage than the airlines allow. They
have to pay extra money for it. They carry 52 kgs together and pay $60 and $100
respectively. Now, if the same luggage was carried by only Ganesh it would cost him
$340. If the airlines charges only at one rate for extra luggage what is the maximum
luggage that a person can carry without paying extra?
