**How to get volume from density and mass?**

One cannot get the volume of a substance from only the density of the substance. The mass of the substance is also required to know. Because there is a relation between the density, volume and mass of a substance as **Volume = mass × density**.

If **m** and **d **be the mass and density of the substance respectively, then the formula for volume of the substance will be **V= m×d** ………(1).

Using equation-(1) one can find the volume of a substance from its density and mass. Clearly, these three physical quantities are connected to each other. if we know the values of any two among these three quantities, the value of the other quantity can be found easily by a simple mathematics.

**Process to get volume:**

- First
**know the value of density**of the substance. It may be provided you during asking the question. Again, density is a physical property of materials or substances. So, one can easily find it from internet or any physics textbook. For example, pure water has its density of 1 g/cm^{3}in CGS and 1000 kg/m^{3}in SI. - Now, you also
**need the value of mass**of the given substance. If mass is not provided then measure it using**beam balance**or a digital weight machine. - Now, you have the values of mass and density of the substance. So, you can find the volume of the substance by
**multiplying the mass with the****density**i.e. by using above equation-(1).

**Numerical problems on density**

1. **The density of an object is 800 kg/m ^{3}. Find the volume of 2 kg object**.

The formula for volume is, **Volume = mass × density**

or, the volume of the object = 2×800 = 1600 m^{3}……..(Answer)
