A block of wood floats in water with $\frac{2}{3}$ of its volume submerged. Its relative density is:

Q. A block of wood floats in water with two-thirds of its volume submerged. Its relative density is equal to

Q. A block of wood floats in water with two third of its volume submerged. In oil, the block floats with $0.90$ of its volume submerged. The densities of (a) wood and (b) oil are [Density of water is ${10}^{3}kg/m^3$]

Q. A block of wood is floating on oil with half of its volume submerged. If the density of oil $840kg{m}^{-3}$, the relative density of wood (relative to water) is:

Q. A wooden block floats in water with two-third of its volume submerged. The density of wood is $Xkg{m}^{-3}$. Find $X$.

Q. A block of wood floats in a liquid of density $0.8gc{m}^{-3}$ with one fourth of its volume submerged. In oil the block floats with $60$% of its volume submerged. Find the density of (a) wood and (b) oil
