I have a box of tiles 12" x 12" - how many tiles will I need for a 9 foot x 12 foot room?
9 * 12 = 108 tiles
To determine the number of tiles you'll need for a 9-foot x 12-foot room, you need to convert the measurements to the same unit. Since you have tiles in inches, it is best to convert the room measurements to inches as well.
To convert feet to inches, multiply the number of feet by 12 because there are 12 inches in one foot:
9 feet x 12 inches/foot = 108 inches
12 feet x 12 inches/foot = 144 inches
Now that you have the room measurements in inches, you can calculate the number of tiles needed. Since each tile is 12 inches x 12 inches, you can find the area covered by a single tile:
12 inches x 12 inches = 144 square inches
Next, calculate the area of the room in square inches:
108 inches x 144 inches = 15,552 square inches
Finally, divide the total room area by the area of a single tile to determine the number of tiles needed:
15,552 square inches รท 144 square inches/tile = 108 tiles
Therefore, you will need 108 tiles for a 9-foot x 12-foot room when using 12" x 12" tiles.
