At the Ho! Ho! Ho! Christmas Tree Farm two lumberjacks head out to find only 12' high trees to cut. When they get to the trees they realize that they have no idea how tall any of the trees are. But they do know that Tim, one of the lumberjacks is 6' tall and at that time of day casts a 2'6" shadow. How can the two lumberjacks mark off only 12' trees to cut?
