I remember a question on the math section of the (pre-NCLB!) Pennsylvania yearly assessment tests was how much fencing wire should you buy for a pasture of given characteristics and you worked it out and the perimeter was like 714 yards and I put that down but said it might not be sold in odd sizes and you’d probably have to patch it so get at least 800

years later I had a teacher who had worked as a grader recognize me for that
