67 x 144 (inches per square foot) = 9648 / 324 (18 x 18) = 29.77 tiles
LXW= sq inches Sq Inches divided by 144 (sq inches in a sq foot)= the # of sq ft per tile (It will be about 1.7 but you have to do the math to be exact) 50 sq feet divided by (sq ft per tile) = the number of tiles somewhere between 25 -30 tiles...
13 x 13 (assumed inches) is 13/12 feet x 13/12 feet, so the area of one tile is 169/144 square feet. To cover 100 square feet you need (100)/(169/144) tiles which works out to (100 x 144)/169 = 14400/169 = 85.2, make it 86 tiles
Two tiles of 16 ft*16 ft will cover 512 square feet.
2 feet make up 24 inches
Each tile covers 336 square inches. You have 62,208 square inches to cover. You will need 185.1 tiles, plus extra for damage and shaping.
12 inches make a foot but i am not sure 12 inches make feet...
5 feet= 60 inches
397
48 inches is four feet. (divide inches by 12 to convert to feet).
5 feet= 60 inches
102 inches = 8.5 feet
400. That's because there are four six-by-six tiles in each square foot. 4 tiles per square foot X 100 square feet = 400 tiles.
