In 2002, a gargantuan iceberg broke away from the ross ice sheet in antarctica. it was approximately a rectangle 218 km long, 25.0 km wide, and 250.0 m thick.
a) what is the mass of this iceberg, given that the density of ice is 917 kg/m3?
b) how much heat transfer (in joules) is needed to melt the iceberg?
c) how many years would it take sunlight alone to melt ice this thick, if the ice absorbs an average of 109 w/m2, 12.0 hours per day?
