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?
157 18 by 18 tiles are needed to cover 352 square feet.
128.2 tiles
226 tiles

216- 2x2
It depends on how big the tiles are.
157 18 by 18 tiles are needed to cover 352 square feet.
616 3x6 inch tiles are needed to cover exactly 77 square feet.

6' x 9' (54 square feet) = 6 square yards of tiles needed.
216- 2x2
2400 tiles if you don't get any extra
236 18-inch tiles.
It would be 9 tiles wide by 12 tiles long. That gives you a total of 108 tiles.
