I will not explain exactly how to tile but i will tell you that your floor has to be very flat, an 18" tile is harder to install when there are crowns in floor they are not as forgiving as a 12 or 13" tile and you will have unacceptable lippage in your 18" tile, for installing go to john bridges website.
A 24" by 18" tile is 432 square inches or three square feet.
1/3 x 3/2 = 3/6 Half a square foot
There are 144 18 square inch tiles in an area of 18 square feet.
If each tile is 1 1/2 feet by 1 1/2 feet, use the decimal equivalent to do the math: 1.5 x 1.5 = 2.25 square feet.
d=18in
To convert feet to inches we must first multiply by 12: 583*12=6996 Next we must divide 6996 by 18 6996/18=388.6666 (barred) =389 18in tiles can fit into 583 feet
18 inches=45.72 centimeters
142.22 tiles First, calculate the number of square inches you need by converting : 320 ft²*144 in² 1 ft²=46,080 in² Second, determine the area of the tiles: 18in * 18in = 324 in² Lastly, divide the total area by the area of the tile to determine the number you need: 46,080 in² / 324 in² = 142.22 tiles
There are 2.25 square feet in 1 18" x 18" tile. Counting for NO waste, you would been 71 tile. Since tile this large with surely have some waste you will want to buy around 78 tile.
18*18 = 324 tiles.
Each tile covers 2.25 square feet. This works out to 48 tiles plus spoilage.
The diagonal of an 18x18 tile is 18*sqrt(2) = 25.46 units.
Multiply the two dimensions to get the area. The calculation will give you 2.25 square feet per tile for a total of 1,305 square feet.

It would depend on the precise layout of the room, and how well you can cut tiles if the room isn't some precise multiple of 1.5 feet. In general, a tile that is 18 inches square covers 1.5*1.5=2.25 square feet. Disregarding tile fragments, 350 / 2.25 = 155.5555 tiles.
You may want to use a calculator. 18 in x 18 in =? square inches There are 144 square inches in a square foot. Divide the square inches in one tile by 144. That should equal about 2.25 square feet per tile. 425 divided by the square feet in one tile -- that would give you the number of tiles. It would take about 189 tiles.
