80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
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.
123 will cover it. Get extras.
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
A 12x12 tile is 1 sq foot, so you will need 198 tiles.
You need 0.52, so about a half.because a single 12x12 tile has an area of 144.
100 + 3%waste for cuts = 103.
If you mean 12x12 "inches", then each tile covers 1 square foot. We trust you can take it from there.
