Here’s some math I can get behind. How does one get the most bang for their buck when ordering pizza? Twitter used @fermatslibrary and actually did the math. They discovered one 18-inch pizza actually has more surface area and therefore more toppings than two 12-inch pizzas. In fact, you get 28 more square inches of pizza if you order an 18-inch pizza compared to ordering two 12-inch pizzas. But, if you’re into crust you’ll want to go for the two 12-inch pies, as you’ll get 33 percent more crust compared to one 18-inch pizza. Who else wants pizza for breakfast?
