Always keep in mind that a cube root of six digit number is two digit number so cube root of .000216 is .06 and not .6.

It is a simple problem
(0.000216)= (216/10^6)
(216/10^6)= ((6*6*6)/(10^2*10^2*10^2))
By taking the cube root now
((6*6*6)/(10^2*10^2*10^2))^(1/3)= (6/10^2)
6/100=0.06ans
(0.000216)= (216/10^6)
(216/10^6)= ((6*6*6)/(10^2*10^2*10^2))
By taking the cube root now
((6*6*6)/(10^2*10^2*10^2))^(1/3)= (6/10^2)
6/100=0.06ans
