Why does a circular pizza cut into triangles come in a square box?

Solution

A circle is the easiest shape to make out of a ball of dough.

A square is the easiest shape to make an easily foldable box out of to contain a circular object.

A circle is easily divided into 4, 6, 8, or 10 equal triangular sections with 2, 3, 4, and 5 swipes from the pizza cutter, as opposed to a minimum of 8 for the usual “grid” style pizza cut.

It’s all about efficiency and ease of preparation, which allows companies to produce and deliver pizzas rapidly.
