Question

What is the density of an object that has mass of 8 kg and a volume of 5.5 m³?

Answer 1

`\large\boxed{density=(16)/(11)\ (kg)/(m^3)\approx1.45\ (kg)/(m^3)}`

Explanation:

`density=(mass)/(volume)\\\\\text{We have}\\\\mass=8kg\\\\volume=5.5m^3\\\\\text{substitute:}\\\\density=(8kg)/(5.5m^3)=(8\cdot10)/(5.5\cdot10)\ (kg)/(m^3)=(80)/(55)\ (kg)/(m^3)=(80:5)/(55:5)\ (kg)/(m^3)=(16)/(11)\ (kg)/(m^3)`
