Is a plywood casket made of cardboard with folds and ridges?

A plywood casket is typically constructed from thin sheets of wood veneer that are glued together, providing sturdiness and durability. It is not made of cardboard; rather, it utilizes layers of wood that offer a more traditional look and feel compared to options like cardboard or composite materials. Plywood caskets are generally designed to provide structural integrity, which cardboard cannot offer due to its inherent properties.

Cardboard caskets, on the other hand, are made from compressed paper material and can be easily folded, featuring ridges that help in shaping. These distinctions highlight that plywood and cardboard are different materials used for different purposes, and this specificity reinforces why the assertion that a plywood casket is made of cardboard is incorrect. Therefore, the answer is accurately identified as 'No'.
