The answer will depend on the size of the tiles. While the numbers are given, there are no units.
So one 16 ft x 16 ft tile will be more than sufficient but you will need over 65 thousand tiles of size 16mm x 16mm.
56 16x16" tiles are needed.
205.3125 tiles exactly OR 206 tiles, with a bit left over!
297 16x16-inch tiles.
Assuming you mean 16x16 inches tiles... 441 tiles would cover the area exactly

To determine how many 16x16 tiles are needed to cover 240 square feet, first calculate the area of one tile. A 16x16 tile has an area of 16 square feet (16 inches = 1.33 feet, so 1.33 x 1.33 = approximately 1.78 square feet). Next, divide the total area to be covered by the area of one tile: 240 sq ft ÷ 1.78 sq ft ≈ 135 tiles. Therefore, approximately 135 tiles are needed to cover 240 square feet.
150 16x16" tiles; you'll have a small part of one tile left over.

16 inch x 16 inch = 16x16/144 = 1.777777.... sq.ft. 450/1.777777..... = 253.125 tiles (not counting any wastage caused by cutting, breakage, etc) = 254 tiles minimum.
