Answer: We know that one cubic meter is equal to 1000 litre
So 40 litre = 40/1000 = 0.04 m 3
Mass of 40 litre of petrol = density × volume = (700 kg/m3) × (0.04 m 3) = 28 kg
Mass petrol tank when filled completely with a fuel of density 700 kg/m3 = 8.0kg + 28 kg = 36 kg
So 40 litre = 40/1000 = 0.04 m 3
Mass of 40 litre of petrol = density × volume = (700 kg/m3) × (0.04 m 3) = 28 kg
Mass petrol tank when filled completely with a fuel of density 700 kg/m3 = 8.0kg + 28 kg = 36 kg
