A simple warehousing problem.

Supplier S sends us its products in a shipping package that is 30" x 30" x 20" and varies in weight from 425 lbs to 575 lbs. I have to overstock it using GMA pallets on racking that is rated for 6000 lbs. Company rules limit store-made pallets to 4' tall. (Nobody follows that rule.)

Question: will my pallet cube out or weight out, and if the latter, at what height?

Like I always say, if you don't use math at work, I don't think you're doing any work.
