9,216 tiles, this is how I worked it out
64 sq feet = 589,824 sq inches
8" x 8" tile = 64 sq inches
589,824 divided by 64 = 9,216
=======================================
The first contributor's arithmetic and writing are both impeccable.
Unfortunately, instead of an area of "64 square feet", he used a 64-foot square.
64 square feet = (64 x 144) = 9,216 square inches.
Each tile = (8 x 8) = 64 square inches
Number if tiles = (9,216/64) = 144 tiles.
Assuming no gap, grout, etc.
It is not clear what is meant by an "18x18 square feet" tile. 18ft * 18 ft = 324 square feet, so that one tile will be more than enough. An 18 inch by 18 inch tile cannot be a 18x18 square feet tile.

abswer is 6.9218 square feet
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
As 8 feet x 8 feet = 64 square feet it will only take one 8 feet by 8 feet tile to cover 64 square feet.

1/144 of square foot
1.78 square feet.
It will cover an area of approximately 408.33 square feet.
To determine how many 16-inch by 16-inch tiles are needed to cover 84 square feet, first convert the tile size to square feet. Each tile is 16 inches by 16 inches, which is 1.33 feet by 1.33 feet, resulting in approximately 1.78 square feet per tile. Next, divide 84 square feet by 1.78 square feet per tile, which equals about 47.2. Therefore, you would need 48 tiles to cover 84 square feet.
5,184 2-square-inch tiles are needed.
440 6-inch square tiles.
