Ответ:
The density of the wood : 1.45 g/cm³
Further explanationDensity is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density
m = mass
v = volume
Volume of the wood![\tt V=2.7\times 5.5\times 3.9=57.915~cm^3](/tpl/images/0824/2729/42952.png)
