Question

The mass of an empty 40 litre petrol tank of a vehicle is 8 kg. What will be its mass when filled with a fuel of density 700 kg/m3.

Answer 1

fuel density = 700kg/m3
volume = 40l = 0.04 m3
mass of fuel = 700 × 0.04 = 28kg

mass when filled = 8 + 28 = 36kg

Answer 2

Answer: 36 kg

Explanation: fuel density = 700kg/m3

volume = 40l = 0.04 m3

mass of fuel = 700 × 0.04 = 28kg

mass when filled = 8 + 28 = 36kg
