A piece of copper having an internal cavity weighs 264 g in air and 221 g in water. If the density of copper is $8.8 g / cm^{3}$ , find the volume of the cavity :-

Options:

Answer:

Solution:

The loss of apparent weight equals the weight of displaced water:
$v_{body} = \frac{264 - 221}{1} = 43 cm^{3}$
$v_{Cu} = \frac{264}{8.8} = 30 cm^{3}$
$v_{cavity} = 43 - 30 = 13 cm^{3}$
