    The objects are similar, and it gives you heights of both (H1 and H2). It follows that if the ratio of heights is H1: H2, then the ratio of volumes is (H1)^3 : (H2)^3. Does that help?

    I got 700 grams for the first one. so using ratios 35cm=500g and if you divide by 35 you get 1cm=14.285714. You need to find the weight of the larger box so you * by 49 which gives you 700g. Not sure if i'm right but try doing the other one, hope this helps.

    Ah, but you're assuming that the width and length remain the same each time, which I don't think is the case here.

    Find the scale factor: Lay it out like this

    35cm=500g, 49cm=X

    35xY=49
    -35

    Y=14
    (/10, SF=1.4)

    35 x 1.4 = 49 (correct)
    Now do 500 x 1.4
