The amount of water displaced by the block is the volume of the block.
so (volume of water with block in it)-(original volume of water)= volume of block

What force is needed to keep a wooden block of density 720 kg and volume 1.0 m3 under water?
Using the rough rule-of-thumb: 1 liter of water = 1 kg.-- The block sinks until it has displaced 720 liters of water. At that point,the mass of the displaced water has the same weight as the mass of theblock has, and the block sinks no further.-- The block still has 280 liters of its volume above water. If that were submerged,another 280 kg of water would be displaced.-- The additional 280 kg of water would weigh (280 x 9.8) = 2,744 newtons (617.3 pounds).That much additional buoyant force would fight the effort to submerge the block.It takes an additional 2,744 newtons (617.3 pounds) to keep the block under water.
What is the shap e and volume of a block?
It depends on the block! Not all blocks are the same shape nor volume.
What is the density of a rectangular block?
It is the mass of the block divided by its volume.
How could you find the volume of wood using a displacement can?
The piece of wood will float (partially submerged) in water. Filling up a displacement can with water and letting the water drain at the sprout is the starting point. When the water stops draining, place a dry (empty) measuring cylinder to collect water coming out of the sprout from here on. Gently lower the wood block on the water. It floats. Gently push the block down until it is just submerged. The volume in the displacement can is the volume of the wood block. The tricky part is how to push the block down without agitating the water, making the reading inaccurate. One possibility is to have a box of known weights around. Carefully place standards on the block without the weights toppling over -- starting with a heavier standard and proceeding to lighter standards (available down to 1 mg). If the standard makes the block submerge below the top surface, start over. Some volume uncertainty will remain for one run. Repeating the exercise and averaging the data will lower the uncertainty. If the piece of wood is irregular -- not a regular shape, we can try the following. find a weight that will let the block submerge completely in water with a string. Measure the volume of water displaced. Then do the weight and string without the piece of wood and measure the volume of water displaced. The difference in volume is the answer for the piece of wood. Again, repeating the experiment reduces the measurement error.
What is the volume of wood block?
If its a cuboid, volume = length * breadth * height .
How is the voime of the waterdisplaced by the grante block compare to the voume of the granite block?
The volume of water is the same.
What mass does metal block displace?
The metal block will displace a volume of water equal to its own volume. By measuring the volume of water displaced, you can then determine the mass of the metal block - as long as you know the density of water (1 gram per cubic centimeter).
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.
A block is placed in a tank of water and floats as shown The water level rises to height Δh1 The block is then taken out and a block of the same weight but smaller volume that also floats is placed?
The water level will rise to a lesser height, Δh2, because the smaller block displaces less water due to its smaller volume, even though it has the same weight as the larger block. This is because an object floats when the weight of the water displaced is equal to the weight of the object itself.
What laboratory instruments would be most appropriate to use in determining the volume of a large block of wood of unknown density?
A graduated cylinder or volumetric flask could be used to measure the displacement of water when the wood block is submerged in it. By measuring the volume of water displaced, you can determine the volume of the wood block. A balance can then be used to measure the mass of the wood block, allowing you to calculate its density.
Are butcher block countertops cheaper than granite countertops?
Butcher block counters are cheaper than granite, however not by much. Butcher block ranges from $40-$65 per square foot and granite is around $40-$100 per square foot.

When the block was placed in the liquid why did the liquid rise?
The matter of the block displaced the water causing the water to rise
Suppose two blocks of identical shape and size were placed in water Block A is made of wood and block B is made of iron How would the buoyant force on these two objects compare?
The buoyant force on both blocks would be equal because it depends on the volume of the object displaced in the water, not the material it's made of. Both blocks would displace the same volume of water, experiencing the same buoyant force.
The reason a granite block is mostly empty space is that the atoms in the granite are?
Yes, this is essentially true. Well over 99.9% of the mass of any atom is in the nucleus. The electrons in their orbitals around that nucleus actually determine the spacial volume that the atom occupies. And on an atomic scale, the distance from the nucleus to the outer boundaries of the electron cloud is enormous. The atom is mostly empty space, and, therefore, anything made up of atoms is mostly empty space.
A block of wood displaced 200 mL of water from a bucket how many Cm3 is the block?
200
How do you calculate the volume of a block?
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
