From multiple layers of veneer glued together.
It is the ultimate strength of a material subjected to tensile loading. In other words, it is the maximum stress developed in a material in a tension test.
The actual wood used could be almost anything, though pine is most common. Plywood is actually a type of manufactured wood with alternating layers glued together with their grain oriented perpendicular to increase the strength.

How much? what kind of plywood floor? Why do you need to do this??
plywood is various types of wood all glued together to create a nice and expensive type of wood. Plywood is also a very soft wood and can be easily damaged.
Yield strength - 13.8 MPa Ultimate tensile strength - 31 MPa

Plywood is made in layers running it opposite directions which give it much more strength than a board that really only has strength in the direction of the grain.
Plywood is a type of manufactured wood made from thin sheets of wood. It is then glued together for greater strength. A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength.
The strength of 1/4 inch plywood is generally lower compared to thicker plywood for heavy-duty applications. Thicker plywood, such as 1/2 inch or 3/4 inch, is more suitable for projects that require greater strength and durability. However, 1/4 inch plywood is commonly used for lighter applications like cabinet backs, drawer bottoms, and craft projects. It is important to consider the specific requirements of your project when choosing the plywood thickness.
Plywood was first used in houses in the early 20th century, gaining popularity for its strength and versatility in construction.
For a roof, plywood with a thickness of at least 5/8 inch is recommended to provide sufficient strength and support.
For a roof, plywood with a thickness of at least 5/8 inch is typically recommended to provide sufficient strength and support.
For flooring, it is recommended to use plywood that is at least 3/4 inch thick to provide sufficient strength and durability.
Plywood's most common use is in exterior sheathing and in flooring substrate. Plywood is also commonly used for concrete form work. Plywood is layered and the layers are oriented at right angles to provide strength and dimensional stability. Plywood also comes in a few thicknesses depending on the application.
MDF (medium-density fiberboard) is generally denser and stronger than plywood, but plywood is more durable and resistant to moisture. MDF is better for indoor use and furniture, while plywood is better for outdoor projects and structural applications.
Plywood has become one of the most popular building materials, thanks to its useful properties such as ability to withstand moisture and high strength
