Arranging Toothpicks into Squares
Date: 10/22/2003 at 00:17:11 From: Erin Subject: Toothpicks We're supposed to make 1 square from 4 toothpicks, 2 squares from 7 toothpicks, 3 squares from 10 toothpicks, and 5 squares from 12 toothpicks. I understand how do all of them except the last one. I cannot draw a picture that uses 12 toothpicks to make 5 squares.
