do you mean 12"x12"? if so 400+3%waste for cuts = 412..so 10 boxes.
20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
You will need at least 66,828 1/4 tiles to cover that area.
Tiles that are two feet on a side cover 4 square feet. 378 of them cover 1512 square feet.
To determine how big a room 35 square feet of tiles would cover, you simply use the area measurement. If the room has a standard rectangular shape, the dimensions can vary; for example, it could cover a room that is 5 feet by 7 feet, or 10 feet by 3.5 feet. Essentially, 35 square feet of tiles will cover any area of that size or smaller.
These 327 tiles will cover an area of 383.8 square feet.
Each tile covers 4 square feet. You will need 24.75 tiles to cover the area.
20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
You will need at least 66,828 1/4 tiles to cover that area.
Each tile covers 81 square inches. You have 1,296 square inches to cover. It will take 16 tiles to cover that area.
Tiles that are two feet on a side cover 4 square feet. 378 of them cover 1512 square feet.
To determine how big a room 35 square feet of tiles would cover, you simply use the area measurement. If the room has a standard rectangular shape, the dimensions can vary; for example, it could cover a room that is 5 feet by 7 feet, or 10 feet by 3.5 feet. Essentially, 35 square feet of tiles will cover any area of that size or smaller.
Multiply the two dimensions to get the area. The calculation will give you 4 square feet for each tile and 100 square feet for 25 tiles.
These 327 tiles will cover an area of 383.8 square feet.
Assuming you mean 16x16 inches tiles... 441 tiles would cover the area exactly
You would need 29 tiles of that size to cover that area (28.77 tiles) to be precise,
To determine how many 12x24 tiles you need for a 26 square foot area, first calculate the area of one tile. A 12x24 tile is 2 square feet (12 inches x 24 inches = 288 square inches; 288 square inches ÷ 144 = 2 square feet). To cover 26 square feet, divide 26 by 2, resulting in 13 tiles. Therefore, you would need 13 tiles to cover the area.
