Plywood sheets consist of an odd number of layers so the grain runs the same direction on both sides.
odd
An odd number times an odd number is an odd number no matter which 2 odds you multiply.
If the last number is odd or even then the whole number is odd or even, in this case the last number is 3 which is an odd number, therefore the whole number is odd.

Plywood sheets consist of an odd number of layers so the grain runs the same direction on both sides.
because that way the surface layer on either side will be pointing in the same direction.
Plywood is made from an odd number of thin wood layers glued with the grain at 90 degrees to the adjacent layer for strength. Hardboard and chipboard come from the remains of other woods.
The layers of plywood are called veneers. Veneers are thin sheets of wood that are glued together to form the plywood panel.
Plywood is made from wood layers called veneers.
Plywood is made from wood layers called veneers.
Plywood is made up of many different layers. These individual layers are called "piles" or "veneers".
When something made of layers such as plywood separates at the layers. Often on finish plywood the top vernier which is the thinnest will come off.
That ensures that the grain in the top and bottom plies run in the same direction.
Often it is known as the "mill stamp" which describes the origin or place of manufacture, the grade stamp (a,b,c or d depending on quality) and often the number of ply's or layers in the plywood.
From multiple layers of veneer glued together.
You get plywood by slicing regular wood into thin layers, and then sticking these layers on top of each other with the grain of one layer running across the grain of the next layer. So plywood, isn't a wood as such, but a wood product, much like particleboard.
