In an iceberg, 15% of the volume projects above the sea surface. If the specific weight of sea water is 10.5 kN/m3 , the specific weight of iceberg ir kN/m3 is

A 12.52

B 9.81

C 8.93

D 7.83

ANS:C - 8.93

The weight of the fluid displaced = weight of the iceberg.
Specific weight of iceberg = 10.5-(15% of 10.5).
= 8.925.
