Tom Rocks Maths Appeal Video 3 – Volume of Prisms

Lesson 3 in our new Tom Rocks Maths Appeal YouTube series is OUT NOW! 

Team Maths Appeal (me and Bobby Seagull) have joined forces with the University of Oxford mathematician, Dr Tom Crawford (aka Tom Rocks Maths) to explore and teach topics from the GCSE Maths syllabus. We aim to show the world that maths is accessible to everyone!

In this episode you will learn the formulae to find the volume of 3D prisms including cubes, cuboids, cylinders. Bobby introduces the topic, Tom explains a memorisation technique for the formulae using his favourite fictional chocolate bars, and I share an interactive tool on GeoGebra – Direct links to each part below.
