What is the minimum thickness of a rubble stone masonry wall?

8 inches
12 inches
16 inches
18 inches

The correct answer is: 8 inches

The minimum thickness of a rubble stone masonry wall is indeed 8 inches. This measurement is significant because it establishes the structural integrity and stability of the wall. Rubble stone masonry involves using rough, uncut stones laid in mortar, and the wall's thickness is crucial for ensuring adequate strength, load-bearing capacity, and resistance to external forces. An 8-inch thickness is often seen as the baseline that provides a balance between structural capability and economical use of materials. Thinner walls may not provide sufficient strength, while thicker walls could lead to unnecessary material costs and excess weight. Understanding this thickness requirement is vital for compliance with building codes and for ensuring the safety and longevity of masonry structures. The other thickness options are generally used in more specialized contexts, where increased load-bearing capacity or specific architectural considerations are required.
