That is 208 square feet. Since the tiles are a square foot each, then in theory, you'd only need 208. But if they are not placed evenly, or you start placing from the center, you might need as many as 28 more (16+13-1).
That would be 6 boxes of floor tile, assuming that you get 40 per box. For the thicker industrial grade tile, you'd get less in a box.

123 will cover it. Get extras.
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.
13 boxes with 13 tiles in each
You would need 111 tile, but with waste you will want to get 125 tile.
