A piece of wood has a volume of 200 cubic centimeters and a density of 0.8 * 10 cubic kilograms per cubic meter. Immerse it in water and let it go. Why can't a piece of wood be suspended The volume of a wood block is 200cm ^ 3, and the density is 0.8 times 10 ^ 3kg / m ^ 3. Let it go after immersing it in the water. Why can't the wood block be suspended in the water? When the wood block finally floats on the water, how large is the volume immersed in the water when it is still?
