Term 2 Week 9

The final week of Perimeter Area and Volume

This week we consolidate this topic and will have an end of topic test Wednesday of week 10.

Volume. We will get our heads around the idea that we can calculate the volume of any prism by multiplying the area of the base times the vertical height.

So if we had a triangular prism (looking at the end you see a triangle) all we have to do is multiply the area of that triangle (1/2 base x height) by the length of the prism.

This is true for any prism - ie any shape that is 'extruded' like pasta. It does not matter how tricky the end looks if we can calculate the area of it then we can work out the volume of the whole shape.
