Plywood consists of which arrangement?

• A. Thin sheets of wood glued together so that the grains are at right angles to one another; an odd number of sheets will be used so that the grain on the front and back will always run the same direction.
• B. A synthetic material with high molecular weight.
• C. A leak bag for body removal.
• D. A surface finished by polishing.

Answer: (A)

Plywood is made by layering thin sheets of wood with the grain of each layer oriented at right angles to the grain of the adjacent layer. This cross-laminated construction gives greater strength and dimensional stability. Using an odd number of layers ensures the grain on the outer faces runs in the same direction, which helps with uniform appearance and finish and reduces warping. The other options describe materials or items that aren’t how plywood is built.
