I am sure someone knows the answer. 128 cu, ft. stacked, but how many cu. ft. loose to make an honest cord of wood.
I'd say too many variables to even hazard a guess . :-\
180-190
State of MN says 160 on 16 inch they also say 110 on corded 16's . I use 200 on 20 inch .
When loading 16" split firewood, we usually figure in a full-sized pickup you can get 1/2 cord if it's carefully stacked, and 1/3 cord if it's thrown in. This would mean that a cord (128 cu ft) should take up 190 cu ft when just thrown in.
As others have mentioned, it's not exact - there are a lot of variables
when i sold firewood i would stack it first in a 4x4x8, then used the conveyor to load into the F250 flatbed, 7.5 wide x 8 foot long x 3 foot metal side racks to see how full the truck got.
then when i had an order for firewood i would just load with the conveyor till i had what looked like more than a cord, about 10-15% over a cord
also looked at the rear tires to see how much they where squished.
the F250 could only just carry the cord
I now have a dodge 1 ton dually that i want to add a flatbed with hydraulic dump like the F250 had.

Kind of like to see how Mn came up with 110.
A cord of stacked cut and split fire wood is 66% wood and 1\3 air.
I don't know it is in the state laws . Also a 128 CF cord is 4 ft. wood not 8 ft. Goes back to when they bought pulp wood 4 feet long . Running a firewood processer you learn real quick that the loggers could care less what length the wood is or if is forked .
There was a discussion of this a bit back:

Which included Maine's legal definition of a "Thrown Cord" for 16" wood would be 180 cubic feet. 195 cubic feet for 24" wood.
