How many boxes of 12x12 tiles in a 117foot room?

Your answer depends on how many tiles come in each box. All brands of tile are different - your boxes may contain 5, 7, 10, 12, 15, or 18 tiles in each box.

Do you mean to say your room is 117 SQUARE feet? If each tile measures 12" x 12" (or one foot by one foot), then each tile is one square foot. With this size of tile, the math is easy. You'd need 117 tiles.

Check the labeling on your boxes, and do the math: 117 square feet divided by the number of tiles in each box. The result is the number of boxes you'll need.
