Question

A cube of wood of volume of 0.2m3 and density 600kg/m3 is placed in a liquid of density 800kg/m3 . What fraction of the volume of the wood be immersed in the liquid
​

Answer 1

Answer:

Given:

Volume of wood = 0.2 m3

Density of wood = 600 kg/m3

Density of liquid = 800 kg/m3

Solution:

Let the fraction of volume of wood inside liquid be ‘v’.

Weight of liquid displaced = weight of the wood

=> (800)(v)(g) = (600)(0.2)(g)

=> v = 120/800 = 0.15 m3

Thus, fraction of the volume of wood inside liquid is = 0.15/2 = 0.075

Answer 2

Answer:

0.075
