Answer: 10

Step-by-step explanation:

      formula for sum of cubes is [n(n+1)]²/4

                                   now, solving gives u n value

                              [n(n+1)]²=12100

                           [ 10 x 11 ]²= [n(n+1)]²

                                      i.e n=10

                              hope u got this
