Take the are of the room and divide it by 6 and there's your answer.If the room is 8 square feet you would need 32 tiles.If the room is 8 by 8 feet you would need 256 tiles.
6 tiles that are 12 ft x 12 ft should be enough.
Assuming you mean 12 by 12 inch (or 1 by 1 foot) tiles, and a 6 by 6 foot room, and also assuming you just want to cover the floor and none of the walls, then the answer is 36, which is the area of the floor in square feet.
Area of room = 5' * 6' = 30 square feet. Assuming the tiles are 12 * 12 square inches (not sq cm) then the area of each tile is 1 square foot and so 30 tiles are needed.
48 will cover it, get 52 in case of breakage.
60 square feet would be 60 one foot square tiles. Get 5 or 6 extra for breakage.
16 x 16 = 256
