Multiply the length of one wall by the height to give you the square footage of that one wall. Then repeat for all other walls in the room and add up the total.
12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
You would need 56 tiles to do the floor
16 square tiles
60 square feet would be 60 one foot square tiles. Get 5 or 6 extra for breakage.
each tile is one square foot so you need 55 tiles
123 tiles

A tile measuring 2 foot by two foot (which, incidentally, is an unusually large tile) has an area of 4 square feet, so it would take 100 such tiles to cover a 400 square foot floor.
Without any waste you would need 25 tiles.
342 of them.
24 of them.
Assuming the room is a square..., sqrt(100) = 10 feet per side ============
