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
157 18 by 18 tiles are needed to cover 352 square feet.
13 in is 1.0833 ft. 1.08332 is 1.174feet squared per tile. 27/1.174 is 23 tiles, give or take a small decimal. Depending on the length compared to width you will likely need to split tiles to have 23 tiles do the job
18 10x10-inch tiles.
If the tiles are 1 foot squares, it will take 1,650 of them to cover 1,650 square feet. If the tiles are 16 inch square (1-1/3 square feet, each), then it would take 1,238 tiles.

The best way to figure out how many 13x13 tile will be needed to cover 30 sf of floor is to calculate 13x13/144 give coverage per tile (1.1736), then take 30/1.736 = 25.56 tiles.
1296 Tiles

192 tiles
616 3x6 inch tiles are needed to cover exactly 77 square feet.
Answer: 184 assuming no waste... There will be waste and broken tiles. Get an extra case. Math: 13in X 13in = 169 Square inches 169 Square inches / 144 Square inches per square foot = 1.17 square foot per tile 215 square feet / 1.17 square feet = 184 tiles
About 17.
