Three tiles should be enough to cover 18 x 20, which is more than enough to cover 14 x 14.

Depends how big the tiles are!
How many 24x24 tiles it take to cover a 14×14 room
In practice you will use more tiles than the equivalent area of the room. A 15 foot strip of tiles will require 15 times 12/13 = 13.846 tiles to cover it. This will have to be rounded to 14 tiles. That means that the 15 foot by 15 foot room will require 14 times 14 tiles = 196 tiles to cover it. And that's if you don't drop and break any or mess up one or more cuts.

If the tiles are 13 in square, an unusual size, there will be 16 one way and 14 the other (ignoring fractions of a tile) so you need 224 tiles.

You will need 140 tiles (10 x 14 = 140)
I will assume you mean that the tiles are 14 inches square and that the room is 18 ft by 33 ft. 18 ft is 216 inches, and 33 ft is 396 inches. As a first approximation, the room is 85536 sq inches so dividing this by 14 squared, or 196. we get just over 436.4 squares. However, this is unlikely to be enough with cutting to fit. It's usual to start in the centre of the room and to lay as many full tiles as possible, then to cut tiles to fill in the borders. You'd need about 140 full tiles, depending on exactly where you start. The number of part tiles needed will then depend on whether they have a nap or not. I'd say you need at least another 21 to be sure.
tiles are 12inches by 12inches,and your kitchen measures12feet by 14feet.how many tiles would you need?
On the surface, it will take 42 tiles that are 14" x 14" to tile a room that is 8' x 7' in size. If we have 6 tiles across the room, that'll be 6 x 14" or 84" or 7' across. That's our 7-foor dimension. If we have 7 tiles along the room, that'll be 7 x 14" or 98" or 8'2" along. That's our 8-foot dimension. There are 2" of extra tile that will have to be trimmed. Note that when we actually tile a real room, we have to start in the middle and not in a corner. We'll chalk the floor, set the center tile and tile outward. We'll cut a bit off the tiles of both ends or both sides of the room to make it "look right" when we're finished. Just so you know. And if the question is pointed at that issue (actual tiling of this room as opposed to a simple math problem), you'll be cutting 1" off all the tiles on one end, and 1" off all the tiles on the other end.
14 x 12 = 168 square feet - that is 168 tiles since each is one square foot
