This good practice can be cut on July 3 meters, you can cut 42 as one of 4 meters, not a waste! If you go to the root of the sum of two similar words, then all the better : the first cut of July 3 meters, 168 meters remaining , and so you can use the following approach : that of 4 * 7 = 28168/28 = 6 means that there are 6 combinations , some materials are not wasted ,
