In the Macy's Thanksgiving Day parade, 2000, there was a new float, the Cheerios' bee, and Buzz bee. The jar of honey it was holding contained 36,763 L of helium. The honey jar was 1/10 of the body size. What is the volume of the entire float? If the density of helium is 0.000178g/cm3, what is the mass of the helium for the entire float in Kg? convert and show work and explain for all points
