Complete question :
The Greenland ice sheet contains about 3 million cubic kilometers of ice. If completely melted, this ice would release about 2.2 million cubic kilometers of water, which would spread out over Earth's approximate 343 million square kilometers of ocean surface. How much would the sea level rise?
Answer:
6.4139941 m
Explanation:
Given that:
Volume of water that will be released if ice sheet was melted = 2.2million km³
Area of ocean surface = 343 million km²
Rise in sea level :
Volume of water realeased / Area of ocean surface
2.2 * 10^6 / 343 * 10^6
0.0064139 * 10^(6-6)
0.0064139 * 10^0
0.0064139 * 1
= 0.0064139 km
(0.0064139 * 1000)m = 6.4139941 m
