Question

In 1986, a gargantuan iceberg broke away from the Ross Ice Shelf in Antarctica. It was approximately a rectangle 160 km long, 40.0 km wide, and 250 m thick. What is the mass of this iceberg, given that the density of ice is 917 kg/m3?

Answer 1

Answer:

1.467 x 10^15 kg

Explanation:

Length = 160 km

width = 40 km

height = 250 m

density = 917 kg/m^3

Volume = length x width x height

Volume = 160 x 1000 x 40 x 1000 x 250 = 1.6 x 10^12 m^3

Mass = Volume x density = 1.6 x 10^12 x 917 = 1467.2 x 10^12 kg

                                         = 1.467 x 10^15 kg
