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.

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.
it depends on what wood it is and what ice.
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.
Yes, it is possible for two objects to have the same volume but different densities. Density is a measure of how much mass is contained in a given volume, so two objects with the same volume but different masses will have different densities. For example, one object could be made of a denser material than the other.
Different objects can have the same density if they have different masses and volumes that balance each other out. For example, a small piece of iron and a larger piece of wood can have the same density if the iron is much denser but the wood is much larger in volume. Density is a function of both mass and volume, so objects can have different combinations of these two factors that result in the same density.

Balsa wood is denser than water because its molecules are more tightly packed, resulting in a higher mass per unit volume compared to water. This higher density causes balsa wood to sink in water rather than float.
Kindling ignites more quickly than blocks of wood because it has a larger surface area relative to its volume, allowing it to catch fire and burn more easily. Additionally, kindling is typically less dense than blocks of wood, which makes it easier for oxygen to reach the fire and sustain combustion.
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.
Copper is denser than wood. The density of copper is around 8,960 kg/m^3, whereas the density of wood varies depending on the species, but generally ranges from 300-800 kg/m^3.
