Explanation:
<u>Average Density </u>
The density of an object of mass m and volume V is
If we know the density and the volume occupied by the object, the mass can be computed as
The tank can hold 20 L of gasoline when full. Converting to cubic meters
That's the volume of the gasoline it contains. Knowing the density of the gasoline, we get the mass of gasoline.
To know the total mass of both, we add the 2.5 kg of the tank
The volume of the tank is computed solving for V
The total volume is
The average density is
