We have that The Density and Volume is given as
[tex]\rho=0.67\\\\\V=30cm^3[/tex]
The factors that affect Density are Mass and Volume
From the question we are told that
The piece of wood shown above has a mass of 20 grams.
Wood parameters
2cm
5cm
3cm
Generally the equation for the Volume is mathematically given as
[tex]V=L*B*H\\\\\V=2*5*3\\\\V=30cm^3[/tex]
Generally the equation for the Density is mathematically given as
[tex]\rho=\frac{m}{v}\\\\\\rho=\frac{20}{30}\\\\\rho=0.67[/tex]
Therefore the factors that affect Density are Mass and Volume
