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.

80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles

If you're talking floor tiles as opposed to wall tiles and by 12x12 you mean they are 12 inches square, then the answer is 300. Because each tile is one square foot and a 15'x20' room is 300 square feet. Simple, eh?
Well if 12x12 is one square foot and you have 44 you need to cover figure 10% for breakage (5 tiles) it looks like 50 tiles will do ya
To lay pool tiles, you will need mortar to affix the tiles to the cement pool, you will also need grout for between the tiles and a sponge to clean the tiles.
