how many 4.25"X4.25" tiles to cover a 12'X14' wall

Question

The room is 12'X14' and I want to tile the walls up 5' with 4.25"x4.25" tiles

Answer 1

12 ft=144 inch & 144/4.25=33.88, so need 34 tiles tu go 12 ft

14 ft=168 inch & 168/4.25=39.529, so need 40 tiles

40*34=1360 tiles, provided yu dont ruin NE tiles

rule av thumb be...add 10% for brake tiles

Answer 2

Tiles are to be fixed around the room which has a perimeter of 2(14+12)=52 feet=624 inches. The height of the tiled area is 5 feet=60 inches, so the area to be tiled is 37,440 sq in. The area of a tile is 4.25^2=18.0625 sq in so we need 37440/18.0625=2072.8 tiles, which rounds up to 2073. To cover 5 ft we need 60/4.25=14 tiles. To cover a length of 14' we need 14*12/4.25=39.53 tiles and to cover 12' we need 12*12/4.25=33.88 tiles. So 14 tiles high and 2(33+39)=144 tiles around the room makes 2,016 tiles uncut. The remaining 2073-2016=57 tiles will need trimming to fit.
