This is another video in the measurement, scale and similarity section of the Year 11 General Maths (Units 1 and 2) course. Building on the work we have done before, I now look at how to find the surface area of 3D shapes. Working through cylinders, cones and spheres I show the formulae used alongside lots of worked examples. This is the best video on the internet for Surface area! I deliver my lessons with humour and easy to understand explanations.

This maths video has been created for courses which are delivered in Australia but, as Maths is a constant, it is equally helpful for students in the USA, UK and other countries who are looking for good maths videos for both high school and middle school.
