Mr. Gomez wants to put a ceramic tile border along all four sides of his kitchen wall. Mr. Gomez has measured and knows he needs enough tiles to make three rows with sixty-three tiles in each row on each of his four walls. How many tiles does Mr. Gomez need to make the border? Tiles are sold in boxes with fourteen tiles in each box. How many boxes of tiles does Mr. Gomez need to buy?
this is a bit confusing, but I will say that
3*63 * 4 = 756 tiles
756/14 = 54 boxes
at first it seems he wants to tile all four sides of a single wall. Then you mention all four walls.
