Answer:
[tex]\large\boxed{density=\dfrac{16}{11}\ \dfrac{kg}{m^3}\approx1.45\ \dfrac{kg}{m^3}}[/tex]
Step-by-step explanation:
[tex]density=\dfrac{mass}{volume}\\\\\text{We have}\\\\mass=8kg\\\\volume=5.5m^3\\\\\text{substitute:}\\\\density=\dfrac{8kg}{5.5m^3}=\dfrac{8\cdot10}{5.5\cdot10}\ \dfrac{kg}{m^3}=\dfrac{80}{55}\ \dfrac{kg}{m^3}=\dfrac{80:5}{55:5}\ \dfrac{kg}{m^3}=\dfrac{16}{11}\ \dfrac{kg}{m^3}[/tex]
