Square boxes are easier to make, ship and store flat. Round boxes typically have to be pre-made and are more bulky to transport.
Circular pizza is easier to cut into slices. Also, if the pizza were square, it would look weird.
If a round pizza came in a round box and fit perfectly how would we get a slice out without struggling or making a total mess…we need the edges of empty space to be able to get at the pizza.
Is it possible to make a round box that is hinged and locks? If it is I am pretty sure it would be expensive rather a square box is not only more common but it is cheap aswell
