Antarctica, almost completely covered in ice, has an area
of5,500,000 mi2 with an average height of 7500 ft.
withoutthe ice, the height would only be 1500ft. estimate the mass
of thisice. the density of ice is 0.917 g/cm3.

The mass of ice is

Explanation:

We are given:

Area of Antarctica =      (Conversion factor:    )

Height of Antarctica with ice = 7500 ft.

Height of Antarctica without ice = 1500 ft.

Height of ice = 7500 - 1500 = 6000 ft =     (Conversion factor:  1 ft = 30.48 cm)

To calculate mass of ice, we use the equation:

We are given:

Density of ice =

Volume of ice = Area × Height of ice =

Putting values in above equation, we get:

Hence, the mass of ice is

the answer is minerals.
