Clouds can weigh thousands of pounds due to their liquid water content. Often this content is measured in grams per cubic meter (g/m3 ). Assume that a cumulus cloud occupies a volume of one cubic kilometer, and its liquid water content is 0.2 g/m3 .
(a) What is the volume of this cloud in cubic miles?
(b) How much does the water in the cloud weigh in pounds?
