About this lesson
This is the final video in the Year 11 General Maths (Units 1 and 2) VCE course relating to measurement, scale and similarity. Building on the work from the previous two videos, I look at similar solids (which are basically 3D). We knew, from 2D shapes, that once we knew the ratio of side lengths, we could find the ratio of areas. I look at how we can use the same ideas to find the ratio of volumes for 3D shapes if we know the ratio of side lengths. There are some worked examples and the theory is all explained in a way which just makes sense.
