Worksheet Overview

QUESTION 1 of 10

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.

 

Answer

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.

 

Answer

Mass = Density x Volume

Mass = 2.712 x 12 = 32.5 g
