A 215 kg weather balloon is designed to lift a 2100 kg package. What volume should the balloon have after being inflated with helium in order that the total load can be lifted? (Assume standard temperature and pressure, at which the density of air is ρ_air = 1.29 kg/m³ and the density of helium is ρ_He = 0.179 kg/m³.)
