52, assuming no waste.
12" x 24" =2 sq. ft. divided into 104 sq. ft. = 52
Assuming that 12 x 12 is 12" x 12" (one square foot), then 30 one-square-foot tiles would cover 30 square feet.
You would need 137 (136.23) 16" x 16" tiles to cover 22.5 square meters.
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.
One side of a square is 10 inches long. How many one square inch tiles are needed to cover its area?
If your tiles are 12 inches x 12 inches you would need 144 of them.
A 12x24 tile is 2 square feet. There are 120 tiles that would be needed.
1500 tiles
Tiles that are two feet on a side cover 4 square feet. 378 of them cover 1512 square feet.
49 tiles
81 tiles squared because if it's a square then it would be 9x9 which is 81
500/1.78 = 281 tiles
25 geinus
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.
144
You will need at least 66,828 1/4 tiles to cover that area.
You would need a total of 92 tiles. It would take just over 91 tiles to cover the area given.
