Actually, BOTH are used. You can define density as mass divided by volume (or mass per unit volume).
density = mass/volume
The object's density = (its mass) divided by (its volume)
The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.
The definition of density is: Density = (Mass) divided by (Volume).A simple algebraic operation rearranges this definition to give: Mass = (Density) times (Volume)
density=mass/volume d=m/v
Weight = (density) times (volume)The definition of density is mass/volume .Now [ weight = mass x gravity ], so [ mass = weight/gravity ], and [ density = weight/gravity x volume ] .So Weight = (density) x (volume) x (gravity)
Andrew made a mistake in calculating density by not properly measuring the volume of the object. Density is calculated by dividing the mass of an object by its volume, and if the volume is incorrect, it will lead to an inaccurate density value.
There is no direct relationship between how much mass an object has and it's volume. That is, mass plays no part in calculating the volume, and volume plays not part in determining mass. However, they are related by the equation to calculate the density. Density=Mass/Volume.
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
You need to know the volume of the piece.After the tables the density of oak wood is 0,6-0,9 g/cm3.
First of all please spell 'calculating' correctly; NOT caculating. The equation for calculating density is ;_ Density = mass / volume This can be reduced to '- d = m/v We can insert the units of density , in metric d = m(kg) / v( cm^3) or in Imperial d = m(lb (pounds)) / v (cu.ins(cubic inches)).
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
