First convert a tile into square feet. 18 inches is 1.5 feet so the square footage of a tile is 1.5 x 1.5 = 2.25 sq. ft. Next divide this into the room square footage to see how many you need; 210/2.25 = 93.3 tiles. You next add a few to take care of waste and breakage etc. I would get a least 100 tiles and make sure you can get more if you happen to run short.

12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
15 tiles exactly.
If the tiles are 1 x 1 FOOT, then they cover 118 square feet.If the tiles are 1 x 1 INCH, then they cover (118/144) = 0.8194 square foot (rounded)If the tiles are 1 x 1 METER, then they cover (118 x 3.280842) = 1,270.1 square feet (rounded)
64 nos tiles is required calculation is

Since a 12x12 tile is one square foot, then 38 12x12 tiles will cover 38 square feet.
64 nos tiles is required calculation is
If the 6x12 tiles are in inches, it will take two of them to cover a square foot. You will need 210 of them.

Assuming that 12 x 12 is 12" x 12" (one square foot), then 30 one-square-foot tiles would cover 30 square feet.
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
1 tile = 1.77 of a square foot, 240 Sq.Ft. divided by 1.77 = 135.5 tiles ok
It depends on the size of the tiles and also, to some extent, on the shape of the area that you need to cover.
