160 But buy extra.
100 but get a few extra in case some break.
In theory 1275 tiles. But that assumes that the area to be tiled is "well-behaved" and that there is no wastage.
tiles are 12inches by 12inches,and your kitchen measures12feet by 14feet.how many tiles would you need?
12X14=168 sq feet 12X12 tiles are ONE sq foot each 2X4 area untiled= -8 sq feet looks like 160 sq feet
If the tiles measure 12 inches square then the area of each tile is 1 sq foot. Therefore 1400 tiles are needed to cover an area of 1400 square feet. However, the actual dimensions of the area being tiled can affect the number of tiles required so closer examination is needed.
The area around the sink would take two rows of four tiles each, so that is 8 tiles which will NOT be needed. The whole floor would take twelve rows of fourteen tiles = 12 x 14 = 168. So, if we take away the 8 tiles which won't be needed we are left with 160 tiles.
We ,know that :no. of tiles = area of room /area of tiles .so,no.of tiles =36 X42 /2x2=378
12X12 would be one footXone foot & 1X1=1 so each tile is one sq foot. Length times width is the formula for finding area. the area to be tiled is 4x14 and 14+14+14+14 is 56 sq feet! 56 sq feet = 56 tiles
I am going to assume that you mean 12in x 12in tiles. 12in x 12in tiles are 1 sq ft, so you would need 140 of them to cover 140sq ft. You may need more depending on the shape of the area to be tiled.
