Pat has two sheets of large, square stamps. One sheet consists of  9 stamps arranged in a 3-by-3 square. (That's 3 stamps by 3 stamps, not 3 inches by 3 inches.) The other sheet consists of 100 stamps arranged in a 10-by-10 square. The stamps on each sheet are separated by perforated creases. All the stamps on both sheets are the same shape and size.


The total length of the creases on the 3-by-3 sheet is  18 inches.


How many inches of creases does the 10-by-10 sheet have?
