Pluto has a mass of 1.27×1022 kg and contains about 30% ice. Assume that the density of this ice is the same as it is at −175 ∘C. If humans traveled to Pluto on a spacecraft and were able to remove all of the ice from Pluto, and melt the ice, how many km3 of liquid water would form at 4 ∘C? Express the volume in cubic kilometers to three significant figures.
