'Calculate Density' worksheet

Key stage:  KS 3

Curriculum topic:   Geometry and Measures

Curriculum subtopic:   Derive and Apply Formulae

Difficulty level:  

Worksheet Overview

Density is an example of a compound measure, which is one that involves more than one unit of measurement. 

Density is a measure of mass (e.g. kg, g) in relation to unit volume (e.g. m3, cm3) and can be measured in kg/m3, g/cm3 etc.

 

We calculate densities using the following formula:

 

Density = Mass ÷ Volume

 

Example

A large block of oak has a mass of 185 kg and a volume of 0.25 m3

Find its density in kg/m3.

 

Answer

Density = Mass ÷ Volume = 185 ÷ 0.25 = 740 kg/m3.

 

Now it's over to you to apply this formula to word problems by yourself.
