Question

Antarctica is roughly semicircular in shape with a radius of
2000 km. The average thickness of the ice cover is 3000 m.
How many cubic centimeters of ice does Antarctica contain?
(Ignore the curvature of the Earth.)​

Answer 1

Area of the Antarctica ice A=π×(R)

2

where, R is the radius .

A=(π×2000×2000)m

2

A=1.257×10

13

m

2

Volume of the ice in Antarctica V=A∗H

where, H is the height

V=(1.257×10

13

×3000)m

3

V=3.77×10

16

m

3

Now, to convert cubic meter to cubic cm

V=3.77×10

16

/10

−6

cm

3

V=3.77×10

22

cm
