You first cut the maximum √2 rectangle from a square. Then you can cut 2 small squares from the remaining long rectangle. The leftover paper is a smaller (√2) rectangle. Using this way you can make 2 small squares and 1 large √2 rectangle and 1 small √2 rectangle.without waste. Happy Folding! Sy Chen
