Direct Cubing

 

This method is simple and easy.

If the number is (ab) its cube can be calculated as

              a3     a2b     ab2    b3

                      2a2b   2ab2     

Sum them up taking care of the carryovers.

Consider (16)3

  Writing it as above

         1     6     36    216

              12     72         

       1     18    108   216

 Considering the carryovers


                   1  0  0  0
                         1  8  0  0
                         1  0  8  0 
                             2  1  6
                        4  0  9  6

Therefore we get the answer as 4096
