if square root of a no. lie between 6 and 7 then cube root of this no. will lie between

if square root of no. lies between 6&7 then this no must lie between 36 and 49.Now the cube bigger then 49 is 64 which is cubic root of 4.So the cube root of required number should must be less than 4 similarly the perfect cube which is just smaller than 36 is 27 and its cube root is 3 so the required number should must be more than 3.
