Final answer:
To find the weight of the tank, calculate the volume of the tank and the weight of the gasoline. Then, add the weight of the tank itself.
Explanation:
To find the weight of the tank, we need to calculate the volume of the tank first. The tank is 0.900 m long and 0.500 m wide, so its volume is 0.900 m * 0.500 m = 0.450 m³. We can then multiply the volume by the density of gasoline, which is 0.75 kg/L or 750 kg/m³, to find the weight of the gasoline in the tank.
Weight of gasoline = Volume * Density = 0.450 m³ * 750 kg/m³ = 337.5 kg.
Since 1 kg is approximately equal to 2.20462 pounds, we can convert the weight of the gasoline from kg to pounds:
Weight of gasoline = 337.5 kg * 2.20462 lbs/kg = 745.2 lbs.
Therefore, the weight of the tank, including the gasoline, is 745.2 lbs + 20 lbs (weight of the tank itself) = 765.2 lbs.
