Describe how you could find the density of a cube of metal? (4 marks) (Example from GCSE bitesize)
- Think of key words in the questions to help solve it. For example in this question we need to consider density and the fact that the object is a cube. 2) Remember the equation of density which is : Density = mass/volume3) So to find the density we need to find both mass and volume4) mass of an object can easily be measures using scales. 5) Volume of the object can be found by measurements. As we are looking at a cube we can remember that the volume = width x height x depth. So these values can be measured using a ruler. 6) As we have now found volume and mass, density can be found using the equation that we remembered earlier. note: when writing up the answer consider how many marks the question is worth. 4 marks means that 4 points should be made in the answer.
