How much correx board?

[MOC]

Hi guys, I'm finally making Wigners 5x2 cage, I'm ordering some of this http://www.teacratepackaging.co.uk/correx-board but can't decide how much I will need. Any help would be appreciated!

For a 5x2 one sheet will do.

Thanks you, ordered! So excited for Wigner to have his new cage!
