A block of wood weighs 12 kg and has a relative density 0.6. It is to be in water with 0.9 of its volume immersed. What weight of a metal is needed if the metal is on the top of wood ? [Relative density of metal = 14]

A block of wood weight 4kg and has a relative density of 0.6 it is to be loaded with lead so that it will float in eater with 0.9 of its volume immersed. What weight of lead will be needed (a) if the is on top of the wood, (b) if the lead is attached below the wood ? (density of lead =11,340kgm^(-3) )

A block of wood weight 4 kg and has a relative density 0.6 . It is to be loabed with lead so that it will folat completely immersed. What weight of lead is needed (a) if the lead is on top of the block (b) if the lead is attached below the block ? Density of lead= 11.34xx10^(3) kg m6(-3)

A block of wood of volume 30 "cm"^3 floats in water with 20 "cm"^3 of its volume immersed. Calculate the weight of the block of wood .

A block of wood floats in water with 2/3 of its volume submerged. Its relative density is

If the density of a metal is 8.2 g/cc, its relative density is

Solve the following problems : The density of a metal is 10.8 x 10^3 kg/m^3 . Find the relative density of metal .
