Common wood densities
WebDensity (volumetric mass density or specific mass) is the substance's mass per unit of volume.The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: = where ρ is the density, m is the mass, and V is the volume. In … WebThe density of wood, exclusive of water, varies a great deal within and between species. Density variations within a particular species of approximately 10% should be …
