This article is the result of a coincidence that affirms the problem’s ongoing interest.
Two manuscripts on the box problem were submitted around the same time to The
College Mathematics Journal, one from the quintet Coll, David, Hall, Magnant, and
Wang, and one from Stankewicz. Despite the overlap in content, the authors approach
and generalize the problem in different ways. The editorial board decided to combine
the articles. That work was done by sarah-marie belcastro, Brian Hopkins, and all six
authors.
