Question

Why are pizza boxes square?

Answer 1

"It is much cheaper to mass produce square boxes than round ones since a square box can be made from a single sheet of cardboard. Square boxes are also much easier to store since they can remain flat until needed."

Hope this helped lol :)

Answer 2

They are square because it would be very difficult to fold a circular piece of cardboard and a square provides the safest transportation for the pizza so the crust doesn't grind down like it would if it was circular.

Step-by-step explanation:

The square shape of the traditional pizza box are the easiest and least time consuming to fold.
