Antarctica has an area of about 5.5 million square miles, and is covered with
an ice sheet approximately 5000 feet thick. What is the mass of the Antarctic
ice sheet, to the nearest kg? Ice has a density of 0.92 g/cm3. (5 points)
1 mile is 1.609344 kilometers
1 square mile is 2.5899881 square kilometers
multiply that by 5.5 million and you get 14.244.935 square kilometers
5000 feet is 1524 meters aka 1.524 kilometers
The volume of the ice is length X width X Height
Length and width = 14.244.935 square kilometers
Height = 1.524 kilometers
14.244.935 X 1.524 = 21709280,94 Cubic kilometers
21709280,94 cubic km = 21.709.280.940.000.000.000.000 cubic cm or 2,170928094e+22 cubic cm
Ice has a density of 0.92g/cm3 so 2,170928094e+22 X 0.92 = 1.997253846e+22 grams
which is 1.997253846e+19 Kilograms or 19.972.538.460.000.000.000 Kilograms
now give me those 5 points LOL
