    the way you can do this is you take two sides that are the same... easiest one is the bottom right for this problem ... the ratio is 2:3 so then for volume the only difference would be you take that and cube it since volume is three dimensions so you would get 2^3 = 8 and 3^3 = 27 so 8:27

    oh oops i missed the second one i gave you answers to one and three the second one you would do the same way but instead of cubing it you just square it so 2^2 is 4 and 3^2 is 9 so it should be 4:9 which is choice A
