Density of the material, ρ=3g∕cc
Density of the fluid, σ=7g∕CC
Let the volume of the material be V and n portion of the volume of the block submerged in the fluid.
∴ Weight of the fluid is Vρg and weight of the submerged part is nVσg According to the condition of equilibrium of a floating body.
Vρg‌‌=nVσg
⇒‌‌n‌‌=‌
