The Firewood Cord & Stack Volume Calculator determines the volume of stacked firewood in legal full cords (128 cubic feet), face cords (ricks), and total cubic feet to verify delivery quantities.

### Legal Definitions & Volumetric Formulas Firewood volume measurements convert three-dimensional stack dimensions into legal cord units: - **Stack Volume in Cubic Feet**: $$\text{Volume (cu ft)} = \text{Length (ft)} \times \text{Height (ft)} \times \left( \frac{\text{Log Length (in)}}{12} \right)$$ - **Legal Full Cords (128 Cubic Feet)**: By statutory definition in most jurisdictions, one legal full cord equals 128 tightly stacked cubic feet (traditionally a stack measuring 4 ft high $\times$ 4 ft wide $\times$ 8 ft long): $$\text{Full Cords} = \frac{\text{Volume (cu ft)}}{128}$$ - **Face Cords (Ricks)**: A face cord measures 4 ft high by 8 ft long (32 square feet of face area) at whatever log depth is cut: $$\text{Face Cords} = \frac{\text{Length (ft)} \times \text{Height (ft)}}{32}$$

### Worked Calculation Example Measuring a delivered woodpile stack 16.0 feet long and 4.0 feet high composed of 16-inch cut logs: - **Pile Depth**: $16\text{ inches} / 12 = 1.333\text{ feet}$ - **Total Volume**: $16.0 \times 4.0 \times 1.333 \approx 85.33\text{ cubic feet}$ - **Full Cords**: $85.33 / 128 = 0.67\text{ full cords}$ - **Face Cords**: $(16.0 \times 4.0) / 32 = 64 / 32 = 2.0\text{ face cords}$ - **Rule of Thumb**: With 16-inch logs, exactly 3 face cords equal 1 full cord ($3 \times 16\text{ in} = 48\text{ in} = 4\text{ ft}$).
