What is plywood?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

An engineered wood made of thin layers (plies) of wood glued together, usually with grains alternating for strength

A A type of metal
B A plastic sheet
C An engineered wood made of thin layers (plies) of wood glued together, usually with grains alternating for strength
D A solid piece of natural wood

Why this is the answer

PLYWOOD is an ENGINEERED WOOD made of thin layers ('plies' or veneers) of wood GLUED together, with the grain of each layer usually ALTERNATING (perpendicular) to the next for strength and resistance to warping/splitting. ASVAB Shop Information tests materials. The cross-grain layering makes plywood strong in multiple directions and more dimensionally stable than solid wood. Other engineered woods: MDF (medium-density fiberboard), particleboard, OSB. Knowing plywood is layered, glued wood with alternating grain (for strength) is commonly tested.
