the weight of the water will be more because the wood if floting on top if the water

Why wood swim on the water?
Wood has a lower density than water, and thus the upward buoyant force provided by the water is equal to the weight of the wood submerged. The density of wood less than water, all things are less than water density can float on the water
Which force keeps a piece of wood floating?
It is caused by the difference in density between wood and water.One cubic foot of wood is usually lighter than one cubic foot of water, hence the water goes up a little but the wood goes up more.The overall density of the wood block is less than that of the water, so it floats.The basic principle is that when a solid object is immersed in a fluid, the solid displaces some of the fluid. This causes an upthrust on the solid, equal to the weight of fluid displaced. If the upthrust is equal to the weight of the solid it floats.
Why does a block of wood float higher in saltwater than a block of wood in fresh water?
Boyle's Law - upthrust equals the weight of fluid displaced, so the more dense fluid (salt water) will cause the wood to float higher than the less dense fluid (pure water).

Why does a block of wood held underwater rise to the surface when released?
Because the weight of the wood is less than the weight of an equal volume of water. So when it's completely submerged, the upward buoyant force on it is greater than the downward gravitational force on it. The wood accelerates in the direction of the net force on it, exactly as one wood expect.
A block of wood is floating in water The weight of the part of the block above water is one-third of the block What is the weight of the water displace by the block of wood?
The weight of water displaced by the floating block of wood is exactly equal to the weight of the ENTIRE block of wood, regardless of how much of the wood is above the water level.
Does the wood float in water cause the wood has greater volume than the water?
Yes, in respect of samples of wood and water with the same weight. Before you put the wood in the water, the bulk of the water is supporting a volume of water at the surface, whose shape is the same as the submerged part of the wood. Wood has a lower density so the weight of the wood below the surface is lower than the weight of the water it displaced, and the weight of the wood above the surface makes up the difference, so the water is supporting the same total weight as before.
What part of the block of wood remains immersed in water of density 1000kg per cm cube when the block of wood placed in water has density 700 Kg per m cube?
-- 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.
Does cork dissolve in water?
Cork is a light weight wood product that will float in water.
A piece of iron on top of a piece wood floating in a bathtub If the iron is removed from the wood what happens to the water level in the tub?
This is a factor of many things, for example, the weight of the iron and the wood, the dimensions of the container and how much water there is, but generally the water will rise because if the item is on top of the water displaces its weight in water.

How are the wood block golfball and water alike?
volume,weight and mass
Why a large log of wood float on water but a steel needle sink?
The water extracted by the wood log while floating is of equal weight of the wood or more. For this reason, the log of wood floats while a steel needle sinks.
A piece of oak has a density of 63 how much of the wood will float above water?
37%
Can wood fall apart when soaked?
Yes. The weight of the water, and or other objects can cause the wood to rot and eventually fall apart. In general, most wood will just absorb the water and then dry out naturally without falling apart.
A piece of pine wood floats on the surface of a lake because the water exerts?
An upward force equal to the weight of the displacement water.
