Ceiling tiles are not all the same size, but I have often seen them in the size one foot by one foot.
Type your answer here... You first need to make an assumption that both the tiles are square and the ceiling is square, otherwise there are any number of possible answers. Each tile would therefore measure 2 ft x 2 ft. The ceiling would be 7 tiles x 7 tiles. The width of the ceiling would be 7 tiles x 2 feet = 14 feet.
It depends on how big the tiles are.
56 16x16" tiles are needed.
240 square tiles are needed
6' x 9' (54 square feet) = 6 square yards of tiles needed.
Four tiles are needed.
54 tiles are needed
It would be 9 tiles wide by 12 tiles long. That gives you a total of 108 tiles.
22.2 tiles so buy 23 tiles.
128.2 tiles
