If the volume of two cubes are in the ratio 125:1, the ratio of their edges is:	Choose the correct choice from the following answers
A) 3:1  B) 5:1  C) 3:5  D) 3:7  E) None of these
Explanation:   Let the edges be a and b of two cubes, then   a3/b3=125/1   =&gt;(a/b)3=(5/1)3   a/b=5/1   =&gt;a:b=5:1   Option 5:1
<result>B</result>
