After the sinking of RMS Titanic, US operated the International Ice patrol with the purpose of monitoring the presence and movements of icebergs in the Atlantic and Arctic oceans. Once, they observed a unique tabular iceberg in a form of a rectangle (250 km x 50 km x 300 m). The sun is the only source of heat and the ice absorbs a mean of 98 J/m2-s, 12.5 hrs per day. The exposed area for heating is 250 km x 50 km and the density is 920 kg/m3. What is the total mass of the iceberg? Express answer in kg and in scientific notation with two decimal places. To input: if the answer is 4.78x1025, input 4.78e25.
