Initial data: V (volume of gasoline poured into the car’s tank) = 20 liters (20 dm3; 20 * 10-3 m3).

Reference data: according to the condition ρb (gasoline density) = 710 kg / m3.

We calculate the mass of gasoline poured into the car using the formula: m = ρb * V.

Calculation: m = 710 * 20 * 10-3 = 14.2 kg.

Answer: The mass of the car has increased by 14.2 kilograms.
