About Sum of Cubes Calculator
The Sum of Cubes Calculator is used to calculate the sum of first n cubes or the sum of consecutive cubic numbers from n13 to n23.
Sum of Cubes Formula
The sum of the first n cubes is equal to:
n2(n + 1)2 / 4
The sum of consecutive cubic numbers from n13 to n23 is equal to:
n13 + (n1 + 1)3 + ... + n23 = n22(n2 + 1)2 / 4 - n12(n1 - 1)2 / 4
