7. The List of Timber

The wooden beams of one wooden beam framing must be ordered and supplied exactly to the wooden beam section and wooden beam length.

Why can the wooden beams not be ordered and supplied in m³?

____________________________________________

For better clearness of the order, a list of timber is used. (See Table 4)
