Answer:
0.024m^3
Explanation:
=======
Answer:
=======
Given:-
Mass of the block of wood = 24 kg
Volume of wood = 0.032 m^3
Density of water = 1000kg/m^3
Now,
Density of wood is given by,
\frac{m}{v} = \frac{24}{0.032} \\
\frac{m}{v} = 750 \: kg/m ^{3}
Therefore,
The density of wood is 750kg/m^3
By principle of floatation,
Mass \:of\: wood = Mass\: of\: liquid \:displaced
Therefore,
Mass of liquid displaced = 24kg
Volume of liquid displaced (v),
\frac{m}{v} = \frac{24}{1000} \\
\frac{m}{v} = 0.24m ^{3}
Now,
Since the volume of the wood is equal to the volume of water displaced, it is 0.024m^3
=====
Note:
=====
=> The volume of the wood below the water surface is the volume of water displaced.
=> Buoyant\: force = Weight\: of\: the \:displaced\: water.
