This is a combinatorics problem that has a number of generalizations.
The following video missed the introduction to the activity. In the introduction, Linda Green asked the group what the maximum number of pieces a watermelon could be cut into with four straight cuts. She let the participants think about it and experiment with silly putty and putty knives, before letting a student try his solution on a real watermelon.

There is a nice relation between this lesson and the
