By summing the correct continuous series of cubed numbers it is possible to produce a number which is itself a cube.Summing the cubes of the series of numbers 3+4+5+...+22 yields the result of 64,000, which is the number 40 cubed, and summing the cubes of the numbers 6+7+8+...+30 yields the result of 216,000 which is the number 60 cubed. For anyone interested in the exercise there are surely more long sequences of this type to be determined by those who are determined to find them.
