A 24 inch tile covers 4 square feet. Doing the math gives an answer of 175 tiles, plus some for spoilage and trim.
If that is 2' x 4' it would cover 800 square feet. If it is 2" x 4" it would cover about 5.5 square feet.

Assuming that 12 x 12 is 12" x 12" (one square foot), then 30 one-square-foot tiles would cover 30 square feet.
It will require a minimum of 1,462 tiles. That number will cover about 1,850.34 square feet.
If your tiles are 12 inches x 12 inches you would need 144 of them.
Tiles that are two feet on a side cover 4 square feet. 378 of them cover 1512 square feet.
500/1.78 = 281 tiles
If the tiles are 1 foot squares, it will take 1,650 of them to cover 1,650 square feet. If the tiles are 16 inch square (1-1/3 square feet, each), then it would take 1,238 tiles.
If that is 2' x 4' it would cover 800 square feet. If it is 2" x 4" it would cover about 5.5 square feet.

I'm going to assume that the tiles are square inches, rather than square feet. But they can be converted to 3 square feet, which means 70 of them would cover the space if it were perfectly rectangular. Get 80 to be safe.
Two tiles will suffice since they will cover 36 square feet.
