It depends on the units used for 18 by 18.
For example, two tiles of 18 ft x 18 ft will be enough. On the other hand, you will need just over 1000 tiles measuring 18 cm x 18 cm.
350.
350 !
If it's really square you should need 156 18" tiles to cover 350 square feet. Most tile stores let you return unused tiles, so I suggest you get a few extra. The number needed can change based on the grout space, how many you break and if the area isn't square you may need more. A rule of thumb is to add 10% for waste. That rule would say to buy about 175.
It could be 35x10ft or 70x5ft
It would depend on the precise layout of the room, and how well you can cut tiles if the room isn't some precise multiple of 1.5 feet. In general, a tile that is 18 inches square covers 1.5*1.5=2.25 square feet. Disregarding tile fragments, 350 / 2.25 = 155.5555 tiles.
16X 16 tiles are 256 sq inches each144 sq inches in a sq footdivide the 256 by 144 and you get 1.778 sq foot per tiledivide 350 sq feet by 1.778 and you will know how many tiles196.875 is the exact calculation, if this is HomeworkIf this is a real flooring exercise, there is the grout line and the fact that 16X16 tiles are not fully 16X16 so you have to allow a few extra for trim & finish.
About 197 (196.875) 16" x 16" tiles will feet in that area.
It depends on the units used for measuring the tiles: 17x17 inches, centimetres etc. As you have not specified this we can not answer your question. When asking questions please take care to include ALL the information we need to answer you.
75 SQUARE YARDS EQUAL 75 X 9 OR 675 SQUARE FEET. A CONTAINER COVERS 350 SQUARE FEET,SO 675/350 = 1.928 CONTAINERS NEEDED 1
To determine the number of 12 square tiles that fit into a 350 sq ft room, divide the total area of the room by the area of one tile. In this case, the area of one tile is 12 sq ft. Therefore, 350 sq ft divided by 12 sq ft equals approximately 29.2 tiles. Since you cannot have a fraction of a tile, you would need to round the number down to 29 tiles.
Based on your computation of 350 sq the answer would be 5600. 1750 divided by 5 =350.. so 350 times 16= 5600.
I'm not familiar with a 16 x 16 foot tile. That's rather large. Perhaps 16 inches. If each tile is 16 inches by 16 inches, then that is 256 in² (divide by 144 in² per ft² to get square feet). So each tile is 16/9 ft² (decimal 1.77777....). Divide 350 ÷ (16/9) = 196 7/8, so 197 tiles.
