Let us first gathered the information needed:
Land area of Antarctica = 14,000,000 KM squared
Average thickness of Antarctic ice = 2.15 KM
Earth’s oceans cover a total surface area of 340,000,000 KM2
If the ice melts into water, the resulting water volume is about 5/6 of the original ice.
So after getting the necessary details, let’s do math.
(5/6) * (14,000,000 km) * (2.15 km) = 340,000,000 km
14,000,000km2 x 2.15km = 30,100,000km3
(5/6) x 30,100,000 = 25083333.33 volume of Antarctica’s water.
