Question: 1 / 400

What is the thickness of a wall made from 8 x 8 x 16 units?

6 inches

8 inches

A wall made from 8 x 8 x 16 units refers to concrete masonry units (CMUs), commonly known as cinder blocks. The specified dimensions indicate that each block is 8 inches high, 8 inches wide, and 16 inches long.

The thickness of a wall constructed with these blocks is determined by their width. Since the standard dimensions of these units show that their thickness (or face shell thickness) is 8 inches, the total thickness of the wall made from these blocks is 8 inches. This is a typical thickness for standard masonry walls, providing both structural integrity and sufficient insulation properties for various construction applications.

In summary, the correct thickness of a wall made from 8 x 8 x 16 units is indeed 8 inches, reflecting both the unit's physical dimensions and the conventions used in masonry construction.
