If you know a log's diameter and length, which resource would you consult to estimate its volume?

• A. Volume table
• B. Board feet calculation
• C. Log scaling
• D. Timber industry

Answer: (A)

When you have a log’s diameter and length and you want its volume, the go-to resource is a volume table. These tables are species-specific and give the log’s volume directly for a given small-end diameter and overall length, usually expressed in cubic feet or cubic meters. They’re built from measured logs and account for the taper and form of real logs, so you get a consistent, quick estimate without needing to mill anything. Board feet calculations estimate lumber volume after cutting, using nominal dimensions, which isn’t the same as estimating the volume of the log itself. Log scaling can involve applying log rules to estimate volume, which is a valid approach but is a method rather than a single reference that directly converts diameter and length to volume. The timber industry is a broad field, not a specific tool for this direct conversion.
