You would need 800 tile assuming you had no waste at all.
Since this is unlikely you will need 825 tile.

You'll need 200 18-inch tiles.
it will take 54 ,18x18 pavers. which you will have to cut some on the edge.
It would take approximately 311 tiles plus 5% to 10% waste depending on how you lay your floor out and how many cuts you will have.
exactly 8
18 inches = 1.5 ft, so each tile is 2.25 sq ft, number required = 249/2.25 = 111
A 18x18 paver is 324 sq. inches. A sq.ft. is a 144 sq. inches. So 600 sq.ft x 144 sq inches = 86,400 sq. inches. So take the sq.inches which is 86,400 divide by the sq. inches of the paver 324 is equal to around 267 pavers you will need.
i thinking the room is 17' 6" x 18' to equal 315 sqftbut you still only need 315 ....12" x 12" tilePlus you need to add waste so you need to make the size 18x18 which is 324 sf. of 12x12 tiles
18" is 1.5', so we can discover the number of square feet in one paver by multiplying 1.5 x 1.5 = 2.25 square feet. To fill an area of 14' x 14', or 196 square feet, you would need 196 / 2.25 = 87 pavers, with room for .11 pavers left over. So to cover it completely, 88 pavers would do the trick.
18 inch x 18 inch tile is really (1 and 1/2) feet by (1 and 1/2) feet That is (3/2) x(3/2) square feet = 9/4 square feet. To cover 900 square feet we need (900)/(9/4) = (900) x (4/9) = 100 x 4 = 400 tiles
