How do you find the sum of consecutive cubes?

“The sum of n consecutive cubes is equal to the square of the sum of the first n numbers.” In other words, according to Example 1: 13+23+33+… +n3=n2(n+1)24.

How do you find the sum of the cubes of n natural numbers?

The sum of cubes of n natural numbers means finding the sum of a series of cubes of natural numbers. It can be obtained by using a simple formula S = [n2 (n + 1)2]/4, where S is the sum and n is the number of natural numbers taken.
