There are 12 inches in 1 foot so each tile is 1x1 ft.
This means nine tiles will fit along nine ft and twelve tiles will fit along twelve ft
The area of this would be 9x12 Which is 108
In conclusion 108 12x12 in tiles will cover 9x12 ft
If you mean 12x12 "inches", then each tile covers 1 square foot. We trust you can take it from there.

A 12x12 tile covers 1 square foot (since 12 inches = 1 foot). To cover a 144 square foot area, you would need 144 tiles, as each tile covers 1 square foot. Therefore, you need a total of 144 tiles to completely cover the area.

The tile is bigger than the area that you want to cover (12x12 > 10x11) so one tile will do. <><><><><> However, if you meant 12x12 INCH tiles, and a 10x11 FOOT room, you would need 110 tiles.
If 12x12 is 144... There would be 144 tiles in a box right?
144 tiles

Oh, isn't that just a happy little question! If you have 38 tiles that are each 12x12 inches, they will cover a total of 38 square feet. You see, each tile covers 1 square foot, so when you multiply 38 tiles by 1 square foot, you get 38 square feet. Just imagine all the beautiful patterns and designs you could create with those tiles!
36 tiles. I would hire a tiler if I was you, this doesn't sound like your 'thing'
