Want this question answered?
Density = Mass/Volume so Volume = Mass/Density. Provided the object is solid.
You measure its mass and volume and then density = mass/volume.
Density = Mass/Volume = 5.6grams/20cm2 = 0.28 g/cm3 This is clearly a hollow piece of iron since the density of solid iron is 7.9 g/cm3
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
It is a 3 dimensional object that has density and volume
640 cm3 x D=m/v
mass/volume=density
Density = Mass/Volume so Volume = Mass/Density. Provided the object is solid.
Density= mass/volume
You measure its mass and volume and then density = mass/volume.
Density = Mass/Volume so Volume = Mass/Density Volume = 24.836/1.92 = 12.94 cc
Density = Mass/Volume = 5.6grams/20cm2 = 0.28 g/cm3 This is clearly a hollow piece of iron since the density of solid iron is 7.9 g/cm3
density x volume
Density is weight (mass actually) divided by volume.
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
I think there is not enough information to solve this question, but these formula's might be helpful: density = mass / volume volume = mass / density mass = volume * density
You wouldn't get the right reading of volume of the object, so you're density calculation would be off.
