It is the cost of a single tile
The answer depends on the dimensions used for 8x8. For example, an 8 inch x 8 inch tile will have a different area to an 8 cm x 8 cm tile.
One 18 inch x 18 inch tile = 1.5 ft x 1.5 ft = 2.25 sq ft.400 sq ft x 1 tile/2.25 sq ft = 177.77 = 178 tiles
The diagonal of an 18x18 tile is 18*sqrt(2) = 25.46 units.
Whenever different units are specified in a problem, we need to convert them to one common unit. The total area is given in square meters but the tile measurements are given in cm. So let's convert the tile measurements to meters. Why not convert the total area to square centimeters. Sure you can, only thing is all measurements must be in the same unit. No mixing of units. So the tile size in meters is 0.3m x 0.3m and so the area of a single tile is 0.09 square meter. Divide total area by area of a single tile and you will get the number of tiles needed. Thus the number of tiles needed is 18.5/0.09 = 205.5 tiles, make it 206 tiles.

144 tile assuming you have no waste.
Thinset tile cement.
9" x 9" tile = 81 sq inches 12' x 15' = 144" x 180" 144" x 180" = 25920 sq inches 25920" / 81 = 320 tile I would buy for waste though 345 tile! You always want to have all your tile in 1 dye lot.
12" x 12" tile is 1 square foot.
12" x 24" = 1' x 2' = 2 square feet per tile7' x 10' = 70 square feet on the floor of the roomAssuming that you only want to tile the floor, 70/2 = 35 tiles.
