A block of light balsa wood and a block of heavy teak of the same size, will also have the same volume (which is the space each block occupies).
it is the same because the molecular structure did not change when you cut the wood in half.
Steel.
You times the length by the width by the height to find volume. To find the density do mass divided by volume.
Length times width times height (lwh) is a way to figure out volume. If you try to do it with water displacement, the wood will adorn the water and ruin the calculations.
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water. -- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced its entire weight in water, and floats. -- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.
Copper is denser than wood.
Depends upon whether it's wood or plastic; plastic's possibly more denser.
Iron is denser than wood, i.e. it weighs more by volume.
it is the same because the molecular structure did not change when you cut the wood in half.
Density isn't determined by the size of the specimen but by its mass per unit of volume. An oak branch has the same density as the whole tree it came from--the weights are vastly different, but density is the same.
Most types of wood are not denser than water--they float in/on water. For the wood types that are denser than water, the explanation is that they contain molecules that are denser than water (e.g. resin) and the average distance between molecules is smaller.
Most wood (blocks) float because most wood is less dense than water. However, there are some hardwoods that are denser than water, a block made from one of these would sink.

nah b
It all depends on the wood. Some wood is denser and heavier than others.
Yes there is from wood blocks to sand blocks
Sounds travel better through denser objects and since water is denser than wood, sound travels through it better.
