What are the dimensions of a standard cord of wood?

A standard cord of wood is defined as a unit of measure that establishes the volume of wood stacked. The dimensions of a standard cord are 4 feet high, 4 feet wide, and 8 feet long. This results in a total volume of 128 cubic feet (4 x 4 x 8 = 128). This measurement is important in forestry and wood sales because it provides a standardized way to quantify firewood, ensuring that consumers receive the amount they are paying for.

The other options do not match this standard definition of a cord. For instance, 4'x4'x10' would yield a volume of 160 cubic feet, while 4'x3'x8' and 4'x5'x6' would equate to 96 cubic feet and 120 cubic feet, respectively. Each of these alternative dimensions represents a different volume, which does not conform to the definition of a standard cord. Thus, the answer indicating a cord as 4'x4'x8' is the correct measure.
