120 tiles
assuming you mean 10" by 10" tiles, 200
Is the room 10 by 6 inches? If so you need 5 12 inch tiles. If it is 10 by 6 feet then the answer is 60.

70 tiles. Add an additional 10% for cuts.
Assuming the tiles are 1 foot squares, you would need 10*15 = 150 tiles.
Your question is confusing because you are using two different scales. If your room is 10 ft x 12 ft and the tiles are 2 ft x 2 ft, the answer is 30 tiles.
A square meter is 100 cm x 100 cm, which equals 10,000 square centimeters. Each 10 cm x 10 cm tile has an area of 100 square centimeters. To find how many tiles fit in one square meter, divide 10,000 by 100, resulting in 100 tiles. Therefore, you can fit 100 tiles of 10 cm x 10 cm in one square meter.
It depends on whether the tiles are 18 inch * 18 inch or 18 cm * 18 cm, etc. And also on whether the room is 10ft *10ft or 10 yards*10 yards or 10 metres*10 metres etc.
144/(1.5*1.5) = 64 tiles, but if you are using this to determine how many are needed to tile a room, you need to add at least 10% for edging around the room. So, you probably need at least 71 or more tiles.
