A cubical block of density floats in a liquid of density . If the height of the block is H = 8.0 cm, then the height of the submerged part is ________ cm. [2026]

Question

A cubical block of density $ρ_{b} = 600 {kg/m}^{3}$ floats in a liquid of density $ρ_{e} = 900 {kg/m}^{3}$ . If the height of the block is H = 8.0 cm, then the height of the submerged part is ________ cm. [2026]

$M g = F_{b}$

$d A H g = ρ A h g$

$600 \times 8 cm = 900 \times h$

$h = \frac{16}{3} cm$

$h = 5.3 cm$
