I suppose the tiles are 6 inches by 9 inches (since you did not mention their units of measurement). Convert the two values into feet. So the length of tile is 9/12 or 3/4 foot. The width of tile is 6/12 or 1/2 foot.
Area of one tile is (3/4) x (1/2) = 3/8 square feet.
To find the number of tiles to cover 100 square feet would be (100) / (3/8). Just do this division. That is the answer you seek. Try it. You can do it. The answer may not be a whole number so round it up to the next higher number (this is because hardware stores don't sell fractions of a tile). Good luck!
12 in*12 in = 1 sq foot. 10 ft * 10 ft = 100 sq feet so 100 tiles would be needed - assuming no wastage.
There are 100 cm in a meter, so the wall is 400 cm X 1200 cm. If there is no gap between the tiles: then 400 cm / 4 cm = 100 tiles, and 1200 cm / 4 cm = 300 tiles. So 100 x 300 = 30,000 tiles.
1 m2 = 1m * 1m = 100 cm * 100 cm = 10000 cm2 Each tile = 10cm * 10 cm = 100 cm2 So, number of tiles = 10000/100 = 100
12 can go into a 100 two times
To find the area of the bathroom floor, multiply the width by the length: 1.8m x 2.2m = 3.96 square meters. Since each tile is 5cm x 5cm, or 0.05m x 0.05m, the area of each tile is 0.0025 square meters. Divide the total area of the floor by the area of each tile: 3.96 square meters / 0.0025 square meters = 1584 tiles. Therefore, you would need 1584 5 cm square tiles to tile the floor of the bathroom.

100 of them.
100 + 3%waste for cuts = 103.
You would need 100 tiles - and have some fragments left over.

Five tiles will cover 160 square feet so they will cover 100% of 156 square feet with a little excess. A precise coverage will require 4.875 tiles.
Each tile will cover 100 square inches. 12,000 square feet is 1,728,000 square inches. You will need 17,280 tiles.
One side of a square is 10 inches long. How many one square inch tiles are needed to cover its area?
100: (20 x 20)/(2 x 2)
13 x 13 (assumed inches) is 13/12 feet x 13/12 feet, so the area of one tile is 169/144 square feet. To cover 100 square feet you need (100)/(169/144) tiles which works out to (100 x 144)/169 = 14400/169 = 85.2, make it 86 tiles
