A Mile of Pizza

July 2, 2017

It’s hard enough to eat a long, gooey slice of pizza. Well, try eating a pizza that’s a mile long! In 2016 in Naples, Italy, 250 pizza chefs got together to make the world’s longest pizza. It measured 6,082 feet long, well over 1 mile. The pizza used more than 2 *tons* of flour, 2 tons of fiordilatte cheese, and 3,500 pounds of tomatoes. It was then rolled through 5 giant ovens, each of which needed 25 people to run it. The whole thing weighed 5 tons in total. Check out the math to find out how many people it would take to eat it!

Wee ones: If the pizza used flour, cheese, tomatoes and olive oil, how many ingredients is that?

Little kids: If the pizza used about 2 tons each of flour, cheese and tomatoes, how many tons of food is that?  Bonus: A ton is 2,000 pounds. How many pounds is 6 tons? Count up by 2s (2,000s) to find out!

Big kids: If a person can eat 2 pounds of pizza before feeling way too full, how many people can that 6-ton pizza feed? (Again, a ton has 2,000 pounds)  Bonus: If they gave you 28 slices of your own, and you eat 1 slice per day starting on a Monday, on what day of the week do you eat the last one?

The sky’s the limit: If the 250 pizza makers wanted to work together in equal-sized groups, how many ways could they have split up evenly?

 

 

 

Answers:
Wee ones: 4 ingredients.

Little kids: 6 tons.  Bonus: 12,000 pounds!

Big kids: 6,000 people.  Bonus: On a Sunday. You have an even number of sets of 7, and remember, each set starting on a Monday (day 1) finishes on a Sunday (day 7).

The sky’s the limit: 6 ways, because 250 has a lot of “factors” (numbers that divide into it evenly). They could form:
2 groups of 125 people each
5 groups of 50
10 groups of 25
25 groups of 10
50 groups of 5
and 125 groups of 2.
