## How to Calculate Lumber
### Board Foot Formula
**Board Feet = (Thickness × Width × Length) / 12**
Thickness and width are in inches (nominal), length is in feet. One board foot is a piece 1 inch thick × 12 inches wide × 12 inches long (or 144 cubic inches). Hardwood lumber is priced by the board foot, while dimensional softwood lumber is often priced per linear foot or per piece.

计算示例
20 pieces of 2×6 lumber, 12 ft long, at $5 per board foot.
- Board feet per piece = (2 × 6 × 12) / 12 = 12 BF
- Total board feet = 12 × 20 = 240 BF
- Total linear feet = 12 × 20 = 240 lin ft
- Cost = 240 × $5 = $1,200.00
