On one episode of Myth busters, Adam and Jamie try to make a lead balloon that will float when filled with helium. The balloon they constructed was approximately cubical in shape, and 10 feet on a side. They used a thin lead foil, which gave the finished balloon mass of 11 kilogram.
Part A) Calculate the thickness of the foil?
x = __________ μm
Part B) Find would the lead balloon float if filled with helium? yes or no
Part C) If the balloon does float, find what would be the most mass it could lift in addition to its own mass?
