A gift shop uses two sizes of boxes for presents. These boxes have exactly the same shape. The smaller box is 7in long, and the larger box is 13in long. If 245^2 of wrapping paper is needed to cover the smaller box, how much wrapping paper is needed to cover the larger box?

Question

anonymous · Answer

245^2 means 245 units squared.  

The scale factor from smaller box to larger box is 13/7.  To determine the amount of wrapping needed for the larger box, we multiply 245 by (13/7)^2.

is that right?

anonymous · Answer

13/7 is almost 2.  So (13/7)^2 is almost 4.  245 x 4 is not even close to 207025.
