For plywood learn how to estimate the weight of plywood panels.
Weight of hardwood per cubic foot.
Water content in wood.
Green firewood is wood that has been freshly cut which naturally contains moisture from the tree.
Assuming the wood is a full 6 and not 5 5 that comes out to 6 5 cubic feet of wood volume.
But also note if the moisture content is higher than 12 it could easily weigh more than this.

Seasoned firewood is wood that has been cut and allowed to dry.
Hardwood woods that come from angiosperms.
The density or hardness of wood varies by species and the value is necessary to approximate the weight of lumber by volume.
Hardwood maple silver acer saccharinum 0 440 hardwood maple sugar acer saccharum 0 560 hardwood buckeye yellow sweet aesculus octandra 0 330 hardwood ailanthus tree of heaven ailanthus altissima 0 460 hardwood alder white rhombie leaf alnus rhombifolia 0 370 hardwood alder red alnus rubra 0 370 hardwood canadian serviceberry.
Now green wood can have moisture content anywhere from 30 denser woods to over 200 lighter woods.
Density of wood species.
The most commonly referenced heaviest wood lignum vitae guaiacum officinale has a specific gravity of 1 05 when green which makes its weight about 1365 kg m 3 or 85 pounds per green cubic foot.
So black locust is about 48 pounds per cubic foot so it would weigh 312 pounds.
For example a dense hardwood hickory as an example will weigh more than a softwood pine as an example because a cubic foot of hardwood has more mass than a cubic foot of softwood.
Softwood woods that come from gymnosperms mostly conifers plants.
