i think it is 5:6 but im not sure?

You're right, How did you get that?

anonymous · Answer

yes you are right, volume goes with the cube

anonymous · Answer

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....

ok thank-you!! i forgot how i worked this out it was a few lessons back but i never turned it in so im just checking all my answers before i submit it

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
