    ratio of measurements is 1:3 ratio of volumes (1)^3 :(3)^3 =1:27 ok suppose that h= 6 and the square base has side length= 1cm V=1/3×12×6 V = 2 cm^3 now with the dimensions tripled h = 18 and square side length = 3cm V=1/3×32×18 V = 54 cm^3 the ratio of the volumes is 2:54 or 1: 27 hope this will work :)
