No, the density of wood can vary depending on the species. Hardwoods like oak and cherry tend to be denser than softwoods like pine and cedar. The density of wood is important in determining its strength and suitability for different applications.
You are confusing density with weight. Two pieces of wood of the same density but different sizes have different weights. Density, you could say, is like hardness. If you take a 6 foot piece of wood, and cut 2 feet from it, the two pieces of wood are definitely different weights but the same hardness. Since they came from the same original piece of wood, they almost have to be the same density. There are some types of wood that have such high density that they will not float on water.
Different objects can have the same density if they have different masses and volumes that balance each other out. For example, a small piece of iron and a larger piece of wood can have the same density if the iron is much denser but the wood is much larger in volume. Density is a function of both mass and volume, so objects can have different combinations of these two factors that result in the same density.
Density = Mass/Volume
If a block of wood floats in water, it means that the density of the wood is less than the density of water. This is because objects with a lower density than water will float, while objects with a higher density will sink.
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.

The larger piece will probably have more mass than the smaller one. But if the wood is of the same type and "all things are equal" as regards moisture content, sap content, etc., the density of both pieces of wood will be the same. Density does not depend on the size of a sample. Density is mass per unit of volume. If a large gold nugget and a small gold nugget are compared, the larger nugget will have more mass, but both nuggets will have the same density.
The secret is that copper packs more mass than wood or plastic do into the same volume.
The specific gravity of a substance is the ratio of its density to the density of water. Given that the specific gravity of the wood is 55, we can calculate its density by multiplying the specific gravity by the density of water. Therefore, the density of the wood is 55 x 62.5 = 3437.5.

Density isn't determined by the size of the specimen but by its mass per unit of volume. An oak branch has the same density as the whole tree it came from--the weights are vastly different, but density is the same.
The material (wood), volume (cubic shape), and density (assuming same type of wood) remain constant for the four cubes of wood.
The density of hickory wood is .89.
you separate those items by weight, appearance, and density
Wood has a lower density than water, and thus the upward buoyant force provided by the water is equal to the weight of the wood submerged. The density of wood less than water, all things are less than water density can float on the water
greater density items wood tend to sink, they are heavier then items of less density with same displacement size
