The Goodyear blimp Columbia is filled with 5740 m3 of helium with density ρ=0.18 kg/m3. The ship has a mass of 5430 kg when empty, and the crew for a given flight has a mass of 286 kg. How much payload can the ship carry? Take the density of air to be 1.3 kg/m3.
i'm having trouble forming a formula for this problem, i know i need to use the buoyant force formula. however, i'm having the fact that its in air and not water is confusing me.

The gross lift will be 5740 x (1.3-.18) = 6429 kg.
Net lift will be 6429-5430-286=713 kg minus weight of supplies and fuel.
