It’s not that I disagree with the math, it’s just that I don’t understand the question.

This question:

Why You Should Always Order the Large Pizza

The large? When every pizza place clearly offers an extra-large option?

What is happening to this country?

But…oh, never mind. They just mean because it’s a better value than the smaller one.

Journalist Quoctrung Bui went out for a pie with an engineer friend who, he writes, ordered a “12-inch medium instead of the 8-inch small—because the medium was more than twice as big as the small, and it only cost a little bit more.” Bui, a mathematically inclined fellow, admits: “This sort of blew my mind.”

And, wow, it really does. I never figured the math before. An 8-inch pizza is about 50 square inches; a 12-inch pizza is about 113 square inches.

So unless they’re charging you over twice as much – which they never do – you’re getting a better bargain buying the bigger pizza.

    We did a calculation one time on various sizes, It came out very close to the same $/sq-in. In one case, the next-to-biggest was actually more.

    Homework assignment: make a graph and see how much a zero-inch pizza would cost.
