Mr. Schordine wants to fill up enough helium balloons to allow him to fly through the skies. He weighs 84 kilograms. He knows that every cubic meter of helium is able to lift about 1 kilogram, and the package for the balloons that he bought says that every balloon can be inflated to a sphere with a radius of 0.4 meters. How many balloons would it take to fulfill Mr. Schordine’s dream of flight?
