PCR Dec 2007

Thought I was getting the nag of them until I tried this one!!!

1.1 b- I don't get the 10,000 / 40 or 10,000/ 50 bit.

Why would you do this calculation?

    You are told:
    The 250 ml carton has 40 sq cm of box
    and the 500 ml has 50 sq cm

    I know they are unrealistic, but don't let that sidetrack you

    If you want to look at my answer put this in the subject line of an email:
