The relationship between density, mass and volume can be expressed as the following formula:

- Mass is measured in grams.
- Volume is measured in cubic millilitres.

## Finding the density of an irregularly shaped solid

To find the density of an irregularly shaped solid we need to do practical work. The volume can be found out by measuring the volume of displaced liquid by an object. We can find the volume of these solids with the following steps:

To find an object's volume, we need to do the following practical:

- Weigh the object to find its mass as usual.
- Find the object's volume.

To find an object's volume, we need to do the following practical:
