Answer 2

Answer:

V be the volume of the iceberg, x be the volume out of seawater.

The iceberg is floating in sea water then

Vρ

ice

g=(V−x)ρ

seawater

g

or V×0.9×g=(V−x)1.1gor0.9V=1.1V−1.1x

0.2V=1.1x

∴

V

x

=

1.1

0.2

Percentage of fraction of the volume of iceberg above the level of sea water

v

x

×100=

1.1

0.2

×100=18%
