**Using the example of differently shaped fish tanks, Fran and Dave show how to calculate volumes, in this fun video for use in KS4 maths lessons.**

Fran explains to Dave what a prism is and using some vivid graphics, how to work out the volume of both a cuboid and cylinder. This comes in handy when Fran wants to find a fish tank for her brother.

Dave finds a rather slow, but accurate way of working out the volume of a rectangular fish tank, whilst Fran shares a formula to make it much easier. Volume = Cross-sectional area x Height.
