    height & mass
    A student is 1.7m tall and has a mass of 60Kg. If the dimension of this student shrank by a factor of three(to1/3 previous values) estimate the mass of the shrunk student.

    I think the answer is not 20 and I don't think it is that easy.
    Please help me answer this question. Thank you a lot!!

    Please clarify: By "dimension" do you mean simply the height?

    Yes, 20kg would be the best "guestimate" but of course the subject could "shrink" in height but get fatter.
