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 the
block 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.
The volume will be reduced to a half of its original value. If the mass is (approximately) evenly distributed throughout the wooden block then the mass will also reduce to a half of its original value and the density will not change.
It is the mass of the block divided by its volume.
Density of wood = mass/volume
you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume
Density = Mass/Volume = 13.6 g/cm3
The volume will be reduced to a half of its original value. If the mass is (approximately) evenly distributed throughout the wooden block then the mass will also reduce to a half of its original value and the density will not change.
Density (kg/m3) = mass (kg)/Volume (m3) So to find the density of the wooden block, the triple beam balanced is used to calculate the mass and the metre rule is used to measure the height, length and width of the wooden block. Then the volume is calculated by multiplying the thee distances obtained from the ruler. Finally the density is calculated using the equation: Density (kg/m3) = mass (kg)/Volume (m3)
1000 kg/ 2 m3 = 500 kg per cubic meter density or 0.5 g/cm3 or approximately half the density of water
Density = Mass/Volume
Density means mass per unit volume. Hence, mass of a body divided by it's volume will give us it's density. Here mass = 4g, volume= 5cm3 So, density = mass/volume =4g/5cm3 =0.8g/cm3 This is the average density of the wooden block. The density of block whole throughout it's body may not always be equal to this value. Some portions of block can be more dense and some less dense. But the average density of any body having mass= 4g and volume = 5cm3 is always 0.8g/cm3 .
It is the mass of the block divided by its volume.
4096 cm is not a volume, but a length. Once you know the volume, divide the mass by the volume to get the density.
The block's density is about 0.076 g/cm3
What is the density of a plastic block with a mass of 2.0 grams and a volume of 2.5cm3?
It depends on the volume of the block and the mass. The equation D=M/V Density=mass/volume The answered is displayed as (answer) grams/(the units in which you measured the volume) I hope this helps.
Density of wood = mass/volume
depends on its size and the density of the wood.
