Density is defined as the mass divided by volume.
Density is also known by the name of viscosity.
Density is denoted by D.
It's unit is basically denoted by kg/m^3.
The density of the block is 0.42 g/cm^3.
The formula of the density is, Density = mass (m) / volume (v)
Now, it is given in the word problem that,
Mass of pine wood = 27g
Volume = 4^3 = 64 cm^3
Thus, Density = 27 g /64 cm^3 = 0.42 g/cm^3.
Hence, the density of the block of pine would be 0.42 g/cm^3
