The continent Antarctica is almost covered with ice. it has an area of 5,500,000 sq. mi. with an average height of 7500 ft. Without the ice, the height would only be 1500 ft. Calculate the mass of the ice (in kg) to the correct number of sig figs. the density of the ice is d=0.917 g/cm3. find the conversion factors youll need (mi/ft/cm) on the internet.

Solution

Height of ice = 7500 - 1500 = 6000 ft = 1828.8 metre 1 ft = 0.3038 metre

Density = 0.917 gram/ cm^3 = 917 Kg/ Metre^3 1 cm = 0.01 metre and 1 gm = 0.001 Kg

Mass = Density x Volume = Density x area x height = 917 x 5500000 x 1828.8 = 9223552800000 Kg
