12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
16 square tiles
13 feet by 12 feet is the same as 156 inches by 144 inches. Multiply 156 by 144 to find that the room's area is 22464 square inches. Next, find the area of each tile by multiplying 13 by 13 to get 169 square inches. We need to find how many 169 square inch tiles can fit in a 22464 square inch room, so divide 22464 by 169 and get 132.923077. Round that up to the nearest whole number and get:133 tiles.
