Estimate wood volume for single or double door frames based on frame cross-section.
📐 Formula & Method
Total Length = (2 × Height) + Width. Volume = Total Length × Frame Width × Frame Thickness × Quantity.
Volume = [(2×H) + W] × w × t × Qty
📋 Worked Example
7ft x 3ft door with 4"x2.5" section: • Length = 7+7+3 = 17ft • Section = 0.33ft x 0.21ft • Volume ≈ 1.18 CFT
