You will need about 1.5 boxed cake mixes, so it is best to prepare 2. Some tall cake pans will require 2 full cake mixes, too.
You will need about 1 package of boxed cake mix for the 8'' and 10'' pan. You might need 1.5 to 2 packages for the 14'' pan.
2 or 3 buy like four boxes and see for yourself
You can get a reasonably thick cake with one box of cake mix.
How deep is the pan? 2" or 3"? It makes a huge difference.
about 1 and a half
for an 14 in round cake pan, you only need 1 box
4 boxes for a single pan
yes, it wont be that tall but it will work ok.
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.

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.
There are 11 cups of batter in an 11x15 pan for a 2 inch layer. I would guess for an 11x13, maybe 10 cups?
Yes. Just be sure to double sift the cake mix and grease the spring form pan. wrong!! you don't have to sift boxed cake mixes!
It depends on how deep the pan is.
Yes there is. This size can be harder to find, at least in most non-specialty stores that carry bakeware, but it can still be found. Brands such as Magic-Line, Fat Daddios, Wilton, and Mad Dadder have 14x14" cake pans.
