The Goodyear blimps, which frequently fly over sporting events, hold approximately 1.90×105ft3 of helium. If the gas is at 25∘C and 1.0 atm, what mass of helium is in the blimp?

I really only need to know how to get the ft3 to liters please

since$$1 ft = 30.48cm$$then$$(1ft)^3 = (30.48cm)^3$$but you have to cube everything, the number AND the unit, so $$1ft^3 = (30.48)^3cm^3$$or$$1ft^3 = 28316cm^3$$Also,$$1L = 1000cm^3$$
