500 sq ft = 500*12*12 = 500*144 = 72000 sq inches
You would need 72000/256 tiles of 16*16 sq inch
ie 281.25 tiles.
The above answer is good only for mathematical purposes. In real life, you would need to take account of the shape of the area and also make an allowance for wastage.
297 16x16-inch tiles.
First I would convert 16x16 inch tiles in feet 16x16 inch tiles = 1.25x1.25 feet tiles To calculate the square feet that one tile takes up multiply 1.25 x 1.25 1.25 x 1.25 = 1.5625 sq feet Now calculate 190/1.5625 to find the number of tiles that can fit in 190 square feet 190/1.5625 = 121.6 You will need 121-122 square tiles
Assuming you mean 16x16 inches tiles... 441 tiles would cover the area exactly
125 16-inch tiles.
Two tiles of 16 ft*16 ft will cover 512 square feet.
56 16x16" tiles are needed.
