Assuming 18x18 refers to 18inch*18inch and not some other measure,
each tile is 1.5'*1.5' = 2.25 sq ft
So number of tiles required = 150/2.25 = 66.66... ie 67 tiles.
That is the mathematical answer. However, this assumes that the 150 sq ft area is a "well behaved" shape and that there are few awkward curves and corners around which the tiles have to be fitted. In real life it is sensible to allow for 10% wastage.

How many 18x18 tiles to cover 150 square feet?
67 tiles.
How many 18 x 18 tile will it take to cover 150 ft²?
18 x 18 (assumed inches) is actually 3/2 feet x 3/2 feet, thus the area of one tile is 9/4 square feet. To cover 150 square feet you would need (150)/(9/4) tiles which is (150) x (4/9) = 200/3 = 66.666, make it 67 tiles
How many 39 x 39 tiles needed to cover 150 sq feet?
Oh, dude, let me break out my calculator for this super exciting math problem. So, if each tile is 39 x 39 square feet, you just divide 150 by the area of one tile, which is 1521 square feet. That gives you about 0.0986 tiles, but since you can't have a fraction of a tile, you'll need 1 whole tile to cover 150 square feet. Math can be so thrilling, right?
How many 16 by 16 inch tiles do you need to cover a 225 square foot room?
Approximately 150 tiles. I would buy 120 at least if possible to start with and if you come up short, the balance of what you need should be easy to figure. If you're buying a stock tile it should be no problem to either return extra for credit or buy more.
How many bricks would you need for 150 square feet?
