Josiah has a mass of 75 kg and wants to know how many helium-filled balloons it would take to fly. The density of helium is about 1 kg / m^3 less than regular air, which means a cubic meter of helium can lift about 1 kg. Fully inflated, a balloon has a diameter of 0.3 m and can be modeled as a sphere. He neglects the mass of the balloon in his calculations. About how many balloons would it take to lift Josiah
