'Calculate Density, Mass and Volume' 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.


You should know the following formulae and may use the triangle to help you remember the three Mass, Density, Volume formulae.




Example 1

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

Find its density in kg/m3.



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


Example 2

Aluminium has a density of 2.712 g/cm3.  Find the mass of a piece of aluminium with a volume of 12 cm3.


Give your answer to 3 sig. figs.



Mass = Density x Volume

Mass = 2.712 x 12 = 32.5 g


Now let's apply these formulae by tackling some questions together!
