To cover 720 sq feet of floor with 18" x 18" tile, you would need 320 tiles.

4 by 4 inches = 1/9 square foot 320 divided by 1/9 = 2880

It depends on the units used for 320x320. Are they 320 mm x 320 mm tiles or 320 cm * 302 cm tiles or some other unit of measurement? It would have helped if you could have been bothered to specify.

16X16 tiles are 1.78 sq ft per tile divide 320 by 1.78

Depends on the size of the tile. Get the area of the tile and then divide by the area you need to fill.

Answer:320 tilesMath:floor is 144 inches X 180 inches144 / 9 = 16180 / 9 = 2020 X 16 = 320 tiles

It depends on the dimension used for measuring the tiles. Whether they are 12 in x 12 in or 12 cm x 12 cm will make a huge difference to the number of tiles required!

There is 144 sq inches in a sq foot so 12 x 15 = 180 sq ft x 144 = 25920 / 81 (9 x 9) = 320 tiles. Be sure to buy extra for waste and mistakes...

To make it easy to calculate I am going to convert everything to inches assuming each tile is 16 inches by 16 inches. I can imagine a 320 sq. ft. room as a 16 feet by 20 feet room. (16 x 20 = 320) 16 feet = 192 inches and 20 feet = 240 inches The area of the room in inches is 192 x 240 = 46080 sq. inches Each tile is 16 x 16 = 256 sq. inches Divide the area of the room by the area of 1 tile: 46080/256 = 180 180 TILES MEASURING 16 X 16 IN. ARE NEEDED TO COVER A ROOM 320 SQ. FEET

320

You need about 310 to 325 12x12 ceramic tiles for a 320 sq-ft room. Many tile dealers let you return unused tile. If your dealer does this, you should over-buy. You will probably break some, and the joint spacing may have an effect on the number of tiles required.

142.22 tiles First, calculate the number of square inches you need by converting : 320 ft²*144 in² 1 ft²=46,080 in² Second, determine the area of the tiles: 18in * 18in = 324 in² Lastly, divide the total area by the area of the tile to determine the number you need: 46,080 in² / 324 in² = 142.22 tiles
