0.8 square meters of tiles need 1.56, and 65 square meters of tiles need at least 102. In addition, cutting and paving will cause loss (it should be enough if all tiles are pasted exactly the same). We usually calculate the loss for customers according to 5%, that is, for every 65,438+000 tiles purchased by customers, at least 3-5 tiles are lost. If the room area is irregular, it is convenient to replenish, and buy 105.
