Order a pizza, and you’ll receive something rather strange.

There is a round pizza in a square cardboard box, and it is cut into triangles.

It’s a common thing that most of us don’t question it.

Consider it for a while, though.

Wouldn’t it make more sense to put a round pizza in a round box?

After all, does this not sound more appropriate?

However, the answer is surprisingly not all about pizza and is more about manufacturing, engineering, and basic economics.

Well, let’s begin with the pizza.

Why is it round?

The answer dates back to the Italian natives who invented pizza hundreds of years ago.

Pizza dough starts out as a ball. The dough will naturally form a circle when the chef pulls it out and spins it around. The round shape is not only traditional, it is also the most convenient shape to have edges that are even, not too thick, and not too thin.

The circle also makes the pizza cook uniformly.

All the points on the rim are at a similar distance from the middle, so the crust is baked evenly in a hot oven.
