A cord of wood is not going to be the equivelant of 128 cubic feet of solid wood. A cord is the amount that will stack into 128 cubic feet including the air space.
The amount of solid wood in a cord vs air space will depend on the shape of the pieces, the consistency of length, and how tightly a person stacks the pieces together. If there are a lot of difference in lengh of the pieces or if there are a lot of odd shaped pieces, that will create more air space and you will have less solid wood per cord. Sometimes pieces, especially hardwood, with a lot of large knots will cause some odd shaped pieces that might not fit together as tight. So this can cause more air space. But then the knots are usully slower growing and more dense wood which has more energy. That may or my not make up for it.
But the main point of all this is, a cord if wood is not an exact measurement. With an inconsistent natural material like firewood, there are just too many variables to come up with a formula to determine the
amount of solid wood in a cord. One person may stack a pile of wood and it will measure a cord. Another person who is better at stacking the wood tightly might stack the same wood and the stack may measure less than a cord. It's just the way it works with firewood.
Hopefully I understood your question right.
