If the apparent weight of a cube of mass \(400\,\text{g}\) immersed in water is \(3.36\,\text{N}\), then the density of the material of the cube (in \(\text{kg m}^{-3}\)) is
\[
(\text{Acceleration due to gravity}=10\,\text{m s}^{-2})
\]
Show Hint
For an immersed body,
\[
\boxed{\text{Apparent weight}=\text{Actual weight}-\text{Buoyant force}.}
\]
Also,
\[
\boxed{F_B=\rho_{\text{liquid}}Vg.}
\]
