How many 13inch x 13inch tiles needed for 150 square foot room?

Answer 1

First you have to change the inches to feet. So you divide 13/12 (because there are 12 inches in one foot). So the tiles are now 1.08 feet x 1.08 feet. Multiply the two sides together to get the area of one tile. 1.08 x 1.08 = 1.16 square feet.

Now divide the whole area of the room (150 square feet) by the area of one tile to find how many tiles are needed.

150/1.16 = 129.3 tiles.

(When ordering tiles you should always order a few more to cover any breakages etc. )
