If you mean 13 inch square tiles:
12 ft x 12 in = 144 inches = 11.08 tiles wide
13 ft x 12 in = 156 inches = 12.00 tiles long
Roughly 11 x 12 tiles = 132 tiles,
but remember the .08 of a tile, which must be repeated 12 times,
which equals .96 of a tile.
So if you are installing them IN CONTACT with each other, then, in theory,
you should be able to do it with 133 tiles,
IF you can successfully cut one tile 12 times accurately without breaking it,
which in practice just wont happen.
If you are going to have a wide grout line between tiles then
132 tiles should do just fine.
HOWEVER it is good practice to get between 5 and 10 percent extra tiles,
in case of breakage or other mess-up.
So i would suggest getting around 140 tiles.
