Density is mass divided by volume. For example kilograms per cubic meter.
To calculate density, divide the mass by the volume. In this case, the density would be 0.8 g/cm³ (density = mass/volume = 400g / 500cm³).
density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
Mass divided by Volume
Mass divided by density
You can't figure out the density from volume alone. You either need to look it up (in this case, the density is independent of the volume), or divide the mass by the volume.You can't figure out the density from volume alone.

-- Measure its mass. -- Measure its volume. -- Divide the mass by the volume. The result of the division is the object's density.
You don't know the density if you only know the mass. You can figure it out if you also know the object's volume.
You can't. There are an infinite number of cylinders with different dimensionsthat all have the same volume, so the volume alone isn't enough informationto tell you the dimensions.
Density = Mass/Volume
Mass is measured by density multiplied by volume. In order to figure out a mass of a rock, one must know its density and its volume measurements.
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
