(Diameter in inches)^2 x Length in feet / 144 = Board Feet
Calculating the Volume of Logs in Cords: A cord is a unit of measurement for firewood. One cord is equal to 128 cubic feet. To calculate the volume of logs in cords, use the following formula:

(Volume in cubic feet) / 128 = Cords
Estimating Drying Time Based on Moisture Content: The drying time for firewood depends on the species of wood, the climate, and the stacking method. A general rule of thumb is that firewood needs to dry for at least six months to reach a moisture content of 20% or less.

Case Study: A Cost-Effective Firewood Project

Let’s look at a case study of a cost-effective firewood project.

Project Goal: Prepare 5 cords of seasoned oak firewood for winter heating.

Location: Rural area with access to public lands.

Resources: 70cc chainsaw, splitting maul, pickup truck, firewood rack.

Cost Breakdown:

Permit Fee: $50
Fuel and Oil: $100
Chainsaw Maintenance: $50
Splitting Maul: (Already owned)
Firewood Rack: (Built from scrap wood – minimal cost)
Transportation: $200 (Fuel and vehicle wear)
Labor: (Self – estimated 40 hours at $20/hour value = $800 – This is an opportunity cost, not a direct cash outlay)

Total Cost: $400 (Direct Cash Outlay) + $800 (Opportunity Cost) = $1200

Cost per Cord: $1200 / 5 cords = $240 per cord

Analysis:

In this case study, the cost of preparing firewood was $240 per cord, which is slightly below the average price of $250 per cord for seasoned firewood. However, it’s important to note that this calculation includes the value of the individual’s labor. If the individual had hired someone to cut, split, and stack the firewood, the cost per cord would have been significantly higher.
