## Key Stage 3

### Meaning

**Volume** is the amount of space an object takes up.

### About Volume

- The
**volume**of a regular solid like a cuboid can be found by using a ruler to measure the length, width and height of an object then multiply those numbers together. - The
**volume**of a liquid can be found by pouring it into a measuring cylinder. - The
**volume**of an irregular solid can be found by pouring water into a measuring cylinder to a known**volume**then placing the irregular solid into the measuring cylinder, making sure it sinks. The water level will increase. This increase is the same as the**volume**of the irregular solid. - There are several common units for measuring
**volume**:

- Metres Cubed - Used for
**volumes**the size of a room or bigger. - Centimetres Cubed - Used for small quantities of liquid.
- Litres - Used on drinks bottles.
- Millilitres - Used for small quantities of liquid.

- Centimetres Cubed and Millilitres are the same
**volume**.

**volume**is the metre cubed. **Volume**is a scalar quantity as it has magnitude but does not have a direction.- There are several common units for measuring
**volume**:

- Metres Cubed - Used for
**volumes**the size of a room or bigger. - Decimetres Cubed - Used for the
**volume**of gases produced in a chemical reaction. 1 mol of gas is 24dm^{3}at standard temperature and pressure. - Centimetres Cubed - Used for small quantities of liquid.
- Litres - Used on drinks bottles.
- Millilitres - Used for small quantities of liquid.

- Centimetres Cubed and Millilitres are the same
**volume**.
