I just finished splitting my 2010 wood and it is now in 3 big piles around my house, ready to get stacked this weekend. Since Geometry was many, many years ago.I'm wondering if there is a way to estimate how much wood is in a pile. For instance, if the base has a diameter of 10 feet and the pile is 5 feet tall, how many cords will that be. I know the slope of the pile will vary but I would guesstimate it at around 50 degrees. Any math whizzes out there?
