    similarity is alwasys seen in terms of one dimension... for eg. lenght breadth or radius or diameter.. and the volume is 3 dimensional so we find the ratio of the radius and then compare....

    By similarity ratio they must mean the length of the side of cube 1 compared to the length of the side of cube 3. They give you the volume of each cube. You know volume = s^3 (side cubed) so find the number so that s*s*s= 125 (s=5) and s*s*s= 216 (s=6) now you take the ratio of their sides to get 5/6
