If Greenland ice sheet melted, approximately how much would the sea level rise worldwide?
(1 meter =3.28 feet)
a. 500 feet
b. 16.4 feet
c. 50 feet
d. 164 feet

How many meters would it rise?

yeah, that's all the question give me. I don't understand it. those are my only answers.

would you be able to help?

you need to find the volume of the ice sheet
Then you need to figure how many m^3 of water that would be when melted
Then you need to find the area of the earth's water surface.
Then divide the icewater volume (m^3) by the earth's watersurface area (m^2), giving the depth increase (m)

Ice Sheet Volume
• Total volume of ice contained in the ice sheet: 2.931 x 106 km3 (Bamber et al. 2001)
o This is the equivalent to an additional 7 m of global sea level rise.
• Ice sheet volume: 2.911080129751762 x 1012 m3 (calculations by R. Huff using Bamber et al. 2001)
• Total ice volume estimated at 2.620 x 106 km3 (Ohmura et al., 1999)
o This is the equivalent to an additional 6.7 m of global sea level rise, without considering the effect of hydroisostacy. 
7*3.28 = 23 feet
If that is all correct
