The sum of the first n cubed numbers is the square of the nth triangular number.
The sum of the first n cubed numbers is: [n*(n+1)/2]2 which is the same as the square of the sum of the first n numbers.
The first 5 cubed numbers are 1x1x1=1, 2x2x2=8, 3x3x3=27, 4x4x4=64 and 5x5x5=125. :)
The first six cube numbers are equal to 1, 2, 3, 4, 5 and 6 cubed. Then these numbers are 1, 8, 27, 64, 125 and 216.
A number can't be cubed and prime. Cubed numbers (other than 1) have more than two factors.

Of the natural numbers, the smallest (excluding 0 and 1 which are the same to any power) cubes are: 8 (2 cubed), 27 (3 cubed), 64 (4 cubed), and 125 (5 cubed).
The first 6 cubed numbers are: 1, 8, 27, 64, 125, 216. 1 ^ 3 = 1 2 ^ 3 = 8 3 ^ 3 = 27 4 ^ 3 = 64 5 ^ 3 = 125 6 ^ 3 = 216
Cubed means multiplied by itself and then multiplied by itself,e.g. 43 means 4x 4=16, 16x4=64,so,43=64
That completely depends on what numbers 'j' and 'k' are, and it changes immediately if either of those changes.
3 cube =27 4 cube =64 5 cube =125 6cube=216 so 3 cubed + 4 cubed + 5 cubed = 6 cubed
4 cubed is 64
