A stack of firewood arranged in a specific, measurable way is a common unit for buying and selling fuel. This configuration typically involves stacking logs neatly in a row, often four feet wide and eight feet long, with the height varying. For instance, a stack four feet high, four feet wide, and eight feet long is commonly considered one-third of a cord.
Using this established measurement provides a standardized method for trading firewood, ensuring clarity and fairness in transactions. It simplifies the process of determining the quantity of wood being purchased or sold. Historically, this method offered a practical way to quantify what would otherwise be a cumbersome volume to estimate. Its consistent application benefits both consumers and suppliers.
