The answer will depend on the units of measurement used for the numbers in the question: feet, metres, centimetres, miles, 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.
67 tile
To cover 720 sq feet of floor with 18" x 18" tile, you would need 320 tiles.
To determine the number of 18 x 18 tiles needed to cover 300 square feet, first calculate the area of one tile. An 18 x 18 tile has an area of 2.25 square feet (18 inches = 1.5 feet, so 1.5 x 1.5 = 2.25). Next, divide the total area to be covered (300 sq ft) by the area of one tile: 300 ÷ 2.25 = approximately 133.33. Therefore, you would need 134 tiles to cover 300 square feet, accounting for any cuts or waste.
Each tile covers 2.25 square feet. This works out to 48 tiles plus spoilage.
18 x 18 (assumed inches) is actually 3/2 feet x 3/2 feet, thus the area of one tile is 9/4 square feet. To cover 150 square feet you would need (150)/(9/4) tiles which is (150) x (4/9) = 200/3 = 66.666, make it 67 tiles
how many 18 x 18 carpet tiles do you need for a 15 x 18 room
To determine how many 3x6 tiles are needed to cover 30 square feet, first calculate the area of one tile. A 3x6 tile has an area of 18 square inches (3 inches x 6 inches). Since there are 144 square inches in a square foot, each tile covers 18/144 = 0.125 square feet. To cover 30 square feet, you would need 30 / 0.125 = 240 tiles.
A 24" by 18" tile is 432 square inches or three square feet.
667 exactly, but you need to factor waste which for tile is 5 to 10% making it 733.
if you are quoting inches, then a 18x18 tile measures 2.25 square feet. On that basis you would need 106.66 or 107 to the nearest.
This scenario seems unlikely. As written, an 18 x 18 foot tile would cover 324 square feet and you'd only need a little more than one to do the job. Even an 18 sq. ft. tile would be unwieldy, although you'd only need 25 of them to cover the space. I'll assume you mean 18 x 18 inches, which is 2.25 square feet. You'll need 195 of those, but get 215 to be safe.
