Remember, just because a problem is NP, doesn't mean it's unsolvable. It just means that there's no (known) way to solve it in polynomial time. All we can do in polynomial time is verify a solution.
There's no reason that one couldn't write an algorithm to solve this problem. The problem is that for any non-trivial number of boxes, it would take a long, long time and/or some pretty expensive hardware to run that algorithm.
