4 boxes for a single pan
Most cake mixes are for a 9x13 pan which is 117 sq. inches. 12x12 is 144 sq. inches. 1 mix would be enough and shorten the cooking time by 5 to 8 minutes.
about 1 and a half
If you are using a 2" deep cake pan you would need 13.5 cups of batter.
for an 14 in round cake pan, you only need 1 box
It depends on how deep the cake pan is.

I would use two and a half, but since that's not possible, I would get two and have extra batter. Mind you, no matter what batter, a cake/brownie must be 3/4 of the way full. hope this helped:)

Okay so here you go! There are approximately 4-5 cups of batter in one cake mix. For a half of a sheet cake, I use 3 cake mixes, so for a full, that's 6. You will have a little bit left over too.
You can figure it out exactly by filling a 9 in cake pan with water and then putting in the cake pan you think might be it (do this 3 times). I'm guessing a deep 9x13 pan. A cake mix usually makes 2 9in cakes, or one 9x13. Hope this is helpful
