My own guess is 14.25 full cords. I used the volume of a cone instead of a partial sphere but a flattish shape like that will end up with almost the same volume. I suspect the differences will be in our assumptions about diameter, height and shrinkage when split, not in the math itself. I sure hope the folks on the pile are close to 6 feet tall because I used that rough number in my assumptions.
Calculator. That's the only way I do too. Well unless you have a face cord, or a third of a cord. .33 of a cord.
Was just thinking if i have a bunch of neat rows, then a part of one at the end, would take cubic feet of that last row, say 60 cubic feet. That would be .47 cord. And gotta break ties somehow.
OK, here is the days summary thus far: Total entries: 31 Range of entries: from 6.0 to 36.93 cords Average of all entries: 14.20 cords Average of all entries throwing out high and low entries: 13.70 Good night, thanks for your entries!
