## Activity

Create prisms using the sliders.
You will need to write down in your maths books the different prisms you make and the volume of them.
For example: Prism 1:
1 layer = 5 cubes x 6 cubes (5 x 6) = 30cm3
7 layers high
Volume = 30 x 7= 210cm3
If you get stuck, create one layer at a time.
You can change the units to metres or cms, just make sure you write the units in your book.
