Answer:
the density of the object is 3.33 [tex]\,\frac{g}{cm^3}[/tex]
Explanation:
Use the formula for density:
[tex]density=\frac{M}{V}[/tex]
where M is the mass of the object, and V its volume.
In our example, we have:
Volume V = 3 x 4 x 2 cubic cm = 24 cubic cm
Then the density is:
[tex]density=\frac{M}{V}=\frac{80}{24} \,\frac{g}{cm^3} =3.33 \,\frac{g}{cm^3}[/tex]
