A block of wood floats in water with two-Third of its volume submerged its relative density is equal to?

Answer 1

Vs = Db/Dw * Vb = 2/3 * Vb = 2Vb/3.
Db/Dw * Vb = 2Vb/3.
Db/Dw = 2/3 = 0.667.
Db=0.667Dw = 0.667 * 0.998=0.665 g/cm^3.
= Density of the block.

Notes:
Vs = Volume submerged.
Db = Density of the block.
Dw = Density of water.
Vb = Volume of the block.
