Expert Answer:

The buoyancy force balances the weight of the cube.

ρsVsg = xρwVsg,

where x is the volume fraction submerged in water, and other symbols have usual meaning.

x = ρsw = 650/1000 = 0.35

Vsubmerged/Vs = 0.35

Ah/0.2A = 0.35, where h is the height of cube submerged in water.

h = 0.07 m = 7 cm.

So  13 cm would the So called distance from water level.
