The volume of wood = 5*3*2=30 cum.
Weight of wood = vol *density of the wood.
The density of wood= SG*density of water.
W = 30*0.75*1000 = 22500 kg.
weight of wood = weight of water displaced.
Therefore vol.of water displaced = weight of water displaced/density.
i.e V=22.5 cum.
Weight of wood = vol *density of the wood.
The density of wood= SG*density of water.
W = 30*0.75*1000 = 22500 kg.
weight of wood = weight of water displaced.
Therefore vol.of water displaced = weight of water displaced/density.
i.e V=22.5 cum.

Maybe 0.75 is specific gravity.

Force = Density*Area*Height.
F = 0.75*2*3*5 = 22.5.
F = 0.75*2*3*5 = 22.5.

Density = Mass/Volume.
Mass = Density x Volume.
Mass = 0.75x2x3x5 = 22.5.
Mass = Density x Volume.
Mass = 0.75x2x3x5 = 22.5.

Answer should be in kg.

How density has no units? it's specific gravity.

M*m*m=m3 Sp Gr has no unit that's why m3 is correct.

C is the correct answer but the only problem is unit. It should be kg.

Specific gravity has no unit but density has unit of kg/m3. In this question density is given so the unit of the answer should be kg but how its comes of m3?
