    I think its best to not worry about it being a cylinder and think about scale factors & volume/SA.

    The weight of water (which corresponds to volume) is 15.6kg-0.8kg=14.8kg

    When you increase length by SF 2, you increase volume by 2^3=8. So 14.8 X 8 = 118.4kg

    The metal sheet (which corresponds to SA) increases by SF 2^2=4. So 4 X 0.8 = 3.2

    Overall, 118.4 + 3.2 =121.6 kg
    See above.

    Question 6, section 1, anybody?
    a) draw a cylinder with base r and length h.
    b) draw a second cylinder with base 2r and length 2h.
    there's only 1 base so dont forget that.

    surface area a) = r^2pi + 2rhpi = 800g = 0.8kg
    surface area b) = 4r^2pi + 8rhpi = 4(r^2pi + 2rhpi) = 0.8 * 4 = 3.2kg

    volume a) = r^2hpi = 15.6kg - 0.8kg = 14.8kg
    volume b) = 4r^2pi*2h = 8r^2hpi = 8*14.8 = 118.4kg.

    add surface area b) + volume b) = 3.2kg + 118.4kg = 121.6kg

    when you get something like this DRAW A DIAGRAM!

    Sounds like a great guy! :p:

    I need it for Oxford and Imperial, and I think I will actually need a lower mark for Oxford than Imperial (for interview anyway!) :eek:

    Well it depends on the % of A*s you have at GCSE. But I'm guessing you didn't do GCSE, so Oxford will put a lot more emphasis on your BMAT score. For me, I have to score around 17 or so I think (judging from an applicant last year, who got an interview with 16.5 last year).

    Yeah true, they will only go mainly by BMAT but seriously don't worry! I'm sure you'll be absolutely fine, and a score of 20+ will put you in very good stead! Have faith in your abilities (and that goes to the rest of you TSRers, you're naturally gonna ace the BMAT, by definition :p:)

    do you have the statistics (or already know!), so i can work out exactly what score i would need with 46% A*s. obv this would be an estimate, but it would be comforting if it is sub 24!

    well if you had 100% A* then you just need to be in the top 60% of applicants

    Well roughly in the top 55-60%, so around 16 on the BMAT. Actually if you get 8A*s out of 8 or 12A*s out of 12 it won't make a difference in what percentile you have to get, which might be a bit unfair I guess.

    well 40% A* you need to be in the top 17% , and 50% A* you need to be in the top 23%, so somewhere in between.

    yeah i understand what your saying! I don't know how Cambridge use my BMAT so i can't really worry too much but with Imperial its lik 19 or we won't even look at you which is kind of depressing!
