The symbol ' as you have used in 16'x16' refers to feet, whereas " refers to inches and I suppose you mean 16"x16" tiles.
16" is 1and 1/3 or 4/3 feet and 16" x 16" = (4/3) x (4/3) square feet, which is equal to 16/9 square feet. So number of tiles to cover 144 square feet is
(144)/(16/9) = 144 x 9/16 = 9 x 9 = 81 tiles
Assuming you mean 16x16 inches tiles... 441 tiles would cover the area exactly
256 sq in = 1.7777 sq ft ea X 56 tiles = 115.55 sq ft area to cover
Well, darling, if each tile is 16x16 square feet, then you just need to divide the total area (150 square feet) by the area of one tile (16x16 square feet) to get your answer. So, 150 divided by 16x16 equals about 5.86 tiles. But since you can't have a fraction of a tile, you'll need to round up to 6 tiles to cover that 150 square feet.
A 10'-0" X 10'-0" area is 120" X 120". 120" divided by 16" = 7.5 tiles. Therefore your room is 7.5 tiles X 7.5 tiles. This equates to 49 full tiles + 14 half tiles (or 7 full tiles) + a tile for the one corner. This totals 57 tiles. I would add extra to cover mistakes when cutting the tiles - check quantity per package and round up.
can you completely cover a 3ftx6ft area with 2ftx2ft tiles
You need just two tiles, so one box of 9 tiles will be more than enough! Alternatively, you could try including the units used for the various measurements.
Depends on how big the tiles are.
You would need a total of 89 tiles (88.88 tiles exactly) with those measurements to cover that area.
Area to be covered = 25 sq ft = 25*12*12 sq inches = 2600 sq inches. So minimum number of tiles required = 3600/(16*16) = 14.06 is 15 tiles. However, that assumes that there is almost no wastage - a very unlikely assumption.
144 Get 160 to be safe.
72 Get 80 to be safe.
It is not possible to answer the question because the area to be covered is not specified. If the area to by covered is 72 feet x 0.25 inches, so that its area is 216 sq inches, then 1 tile should be sufficient. If the area to be covered is 72 feet by 2.5 inches, then 9 tiles will be enough. If the area to be covered is 72 feet x 72 feet, then 2916 tiles will be required. You have not provided all the information required to answer the question properly.
