3^3 = 3 * 3 * 3 = 27
4^3 = 4 * 4 * 4 = 64
5^3 = 5 * 5 * 5 = 125
6^3 = 6 * 6 * 6 = 216

The result of cubic of rational number [tex]\frac{5}{6}[/tex] is  [tex]\frac{125}{216}[/tex].

Taking cubic root of given rational number is,

          [tex]\sqrt[3]{\frac{125}{216} }=\sqrt[3]{\frac{5*5*5}{6*6*6} }=\frac{5}{6}[/tex]

Hence, rational number [tex]\frac{125}{216}[/tex] is cubic of rational number [tex]\frac{5}{6}[/tex].
