Question

In an iceberg, 15% of the volume projects above the sea surface. If the specific weight of sea water is 10.5 kN/m${}^3$, the specific weight of iceberg in kN/m${}^3$ is

• A. $12.52$
• B. $9.81$
• C. $8.93$
• D. $7.83$

Answer 1

The correct option is C $8.93$

Specific weight of iceberg $=(1-0.15)\times 10.5=0.85\times 10.5=8.93kN/m^3$
