Lets start with the basics. A bag of popped popcorn contains roughly 13 cups. Now, knowing that a gallon contains 16 cups, each bag contains roughly 80% of a gallon. Bear in mind that popcorn is filled with air and not compressed, meaning that these calculations could be off.7,000 gallons (why 7,000 gallonsu2026) is the equivalent of 112022 cups!112000/number of cups in a bag of popcorn (13)= 8615 bags of popcorn!A quick search on google shows me that a 12 pack of popcorn is $5.20 (buying in bulk would help). Going off of this price, $5.20*8615= $ 44,798Thatu2019s a lot of fucking popcorn.*I used the ACT II popcorn nutrition facts for the initial measurement.
