Cutting floor out of a full sheet of aluminium

[Shorty]

I've just got round to ordering a full sheet of 3mm aluminium for my floor panel but as the sheet is 2500x1250 I'm assuming I can get more than just the floor panel out of it.
I'm thinking I could at least get the seat back panel out of it too.

Any ideas if I will be able to squeeze anything else out of it?

Not had a measure up but just wondering how others have put theirs to best use.
