Answer:
[tex]\boxed {\boxed {\sf d=0.5 \ g/cm^3}}[/tex]
Explanation:
Density is equal to mass over volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the wood is 6.0 grams and the volume is 12.0 cubic centimeters.
[tex]m= 6.0 \ g \\v= 12.0 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac {6.0 \ g}{12.0 \ cm^3}[/tex]
Divide.
[tex]d=0.5 \ g/cm^3[/tex]
The density of the wood is 0.5 grams per cubic centimeter.
