Depends on the size of the tile. Get the area of the tile and then divide by the area you need to fill.
each tile is 18 x 18 = 324 sq in room is 63 x 144 = 9072 sq in 9072/324 = 28 tiles
Each tile will cover 2 square feet. You have 64 square feet. You will need 32 tiles.
You can't answer how many tile you need since the size of the tile wasn't provided in the question. You will need 100 square feet of tile to cover the area and 10 square feet extra for cuts, breaks, and mistakes. Buy 110 square feet of tile.
A 12x12 tile is 1 sq foot, so you will need 198 tiles.

You will need approximately 142 tiles, accounting 10% waste.
You need3.11 square meters/area of each tile .
50cm x 50cm tile = 7.24/SF per tile 466/7.24 = 64.36 you would need 65 tiles
To cover 720 sq feet of floor with 18" x 18" tile, you would need 320 tiles.
If your tiles are really 25 square feet, you will need 7 of them to cover that area. Might as well get 8 to be safe. I don't know how many are in a box.
You will need 25, 13x13 tiles.
