The volume of two similar solids are 20 cm3 and 2500 cm3 what is the ratio of the corresponding sides of the larger figure to the smaller figure

First, we find the ratio between the volumes of the given solids. That is,
                         r (V_larger / V_smaller) = 2500 cm³ /20 cm³
                              r = 125
To determine the ratio of the corresponding sides of the larger figure to that of the smaller figure, we just have to get the cube root of the ratio calculated above. This will give us an answer of 5 or similarly, 5:1.
