This is another video in the Year 9 series looking at Using Units of Measurement and Measurement and Geometry. Having taken a look at finding the surface area of basic prisms, I now take some time to look at the surface area for more complex prisms and pyramids. There is a great story at the start of the video about camels ... but then I return to the subject at hand; looking at how to find the surface area of a prism. There are lots of worked examples used to explain the theory in a clear and easy to understand way.
