How to Calculate Cubic Feet in a Cord

The formula for volume is:

Formula

$\text{Volume}=\text{Length}\times\text{Width}\times\text{Height}$Volume=Length×Width×Height

---

Step-by-Step Calculation

Step 1: Measure the stack

• Length = 8 ft
• Width = 4 ft
• Height = 4 ft

Step 2: Multiply dimensions

$8\times4\times4=128$8×4×4=128

Step 3: Final Result

• 128 cubic feet

Full Cord vs Face Cord

Many people confuse a full cord with a face cord.

Full Cord

Contains:

$128\ \text{cubic feet}$128 cubic feet

---

Face Cord

A face cord is typically:

• 4 feet high
• 8 feet long
• One log length deep

For 16-inch logs:

$4\times8\times1.33\approx42.7$4×8×1.33≈42.7

Result:

• Approximately 42.7 cubic feet

This is about one-third of a full cord.
