A raftis constructed of wood having a density of 600 kg/m3. The surface area of the bottomof the raft is 5.7 m2, and the volume of the raft is 0.6 m3. When the raft is placed in fresh water having a density of 1 x 103kg/m3, how deep is the bottom of the raft below water level?

The bottom of the raft below water level is 6.6 cm.

Height of the raft

The height of the raft is calculated as follows;

Ah = V

h = V/A

h = (0.6)/(5.7)

h = 0.11 m

Specific gravity of the raft

The fraction of the raft submerged in the fresh is calculated as follows;

[tex]S.G = \frac{\rho_ {raft}}{\rho_{water}} \\\\S.G = \frac{600}{1000} \\\\S.G = 0.6[/tex]

Fraction of the raft below water

The bottom of the raft below water level is calculated as follows;

depth = 0.6 x 0.11

depth = 0.066 m

depth = 6.6 cm

Thus, the bottom of the raft below water level is 6.6 cm.
