# How many square feet of pizza is eaten in the US each year?

34

A pizza is roughly 1 sqft. If the average american eats 1/3 of a pizza and eats pizza 3 times a month, that would mean 12sqft a year. Times 200M americans that gives you 2.4 billion sqft.

These market estimation questions are pretty common in IB and consulting; so this one is not an oddball. The critical part is the logical reasoning used to estimate rather than how accurate you are. Try these: how many diapers used everyday in Canada how many commercial planes are currently flying in US air space

Assume average pizza is 16", or 8" radius. That is 0.66 feet. Square it and mulitply by 3.1 to about (0.4)*3.1 = 1.2 ft^2. Assume 100 million families in US eating one pizza 10 times a year (this is the weakest assumption) = 100,000,000*10*1.2 = 1.2 billion square feet of pizza, +-0.3 billion.

If I wanted the job, I'd say I would research the answer directly. If not found, I would use whatever statistics I can find. An example would be: (# of pizza's sold) times (average sq feet per pizza) times (average ratio of pizza eaten vs thrown away) If I didn't want the job, I'd say "I'm going to research this, then leave for the day, score some good acid, return 24 hours later and make up a number".

The answer is none. Pizza is sold by volume. The correct unit of measure for volume is cubic feet, not square feet. You cannot eat something that has no volume.

Answer is zero, or at least it can't be answered. Question said "US" - not U.S. US is not a measurable subject (whose US?) Question did not ask United States (U.S.) because there was no punctuation marks in their subject US.

MOST PIZZA IS SEVED IN THE SHAPE OF TRIANGLE (FOR A SLICE) OR IN THE SHAPE OF A CIRCLE - NEED TO DO SOME RESERACH AND THEN SOME MATH. LET ME GET BACK TO YOU ABOUT IT.

If i know & see it right, Pizza's are not square in shape so sq feet is not the correct UOM (Unit of measure). Pl correct ur question in terms of circle/diameter/radius & I shall revert with the answer. Trust your question is answered.
