Yes, this is bin packing. There is a module that will do it on CPAN: Algorithm::BinPack. I've also written some code which does this back when I was teaching a class on the topic and needed to be able to compare the various strategies. Generally, if you want the best packing, you just have to try the various strategies and choose the one which makes the most efficient use of space. For any of the strategies, one can construct a scenario where another of the strategies performs better. But, as LanX said, First Fit Decreasing is a usually strong performer.
