Real life story problem help

I plan on filling my buddy's living room with balloons while he is on
vacation, just a little prank. Need help figuring out how many
balloons to buy. Anyone here willing to give me guidance?

What I have figured out on my own, and with my recollection of my 1979
Sophmore geometry class, got a "C":

Front room is approx 12 feet by 16ft, with alcove aprox 8 feet by 8
feet. (192 sq. feet plus 64 sq feet = 256 sq feet total) ceiling is 8
feet, so I believe we have 2048 cubic feet. for simplicity let's say
it is 2k cubic feet.

Now balloons are listed as "12 inches". I am guessing that an
inflated balloon, and empty space around it when it is put in a large
room with other balloons would equal maybe 1.25 cubic feet.

So that leaves me needing approx 1600 ballons???

any critique on this logic let me know, just trying to get a wild idea
of how many balloons I will need.
