Assuming the tiles are 1 foot squares, you would need 10*15 = 150 tiles.
It would be 9 tiles wide by 12 tiles long. That gives you a total of 108 tiles.
You would need 216 tile. Figure how many 2-inch tiles are in one square foot: there are six across and six up/down. That's 36 tiles per square foot. The floor is 3 feet by 2 feet, which is 6 square feet. 6 square feet x 36 tiles is 216 tiles.
17*12 = 204 tiles.
There is not sufficient information to answer the question. Saying that the room is 200 foot long conveys no information at all on its width and, therefore, on the area that needs to be covered by the tiles.
you need to know how wide the floor is in addition to how long. Number of tiles is lenght x width
The answer depends on the shape of the 30 square feet area. If it is in the form of a strip that is 5 inches wide and 72 feet long and you don't want mosaics with little offcuts, then you will require 144 tiles.
Depends how big the tiles are!
half a foot
.666 would be an 8 inch line. To get this, you would divide 8 by 12.
square feet is best understood (for me) in terms of tiles. one tile is a foot long and a foot wide. If you tile a floor with these tiles and you notice that one side of the floor (lenghtwise) is fifteen tiles long and the other side is fifteen tiles across. this means that the room is 15X15 tiles. since our handydandy tiles are 1X1 (recall one foot by one foot) this means that our floor is actually 15X15 square feet. >> don't forget that Ft. squared is math terminology for ft. X ft. (or 15ft.x 15ft.) The dimensions of a room that is 15ft. sq. would probably be around 4X4ft. that is ittsybittsy
