Sum of the Cubes of First n Natural Numbers - Math Only Math

WebApr 5, 2024 · Sum of cube of first n natural number is determine by using the formula which is shown below, ∑ n 3 = n 2 ( n + 1) 2 4. For first 15 natural numbers, we put n = 15 in above equation, ∑ n 3 = 15 2 ( 15 + 1) 2 4 = 15 2 × 16 2 4 = 14400. Mean of cubes of the first 15 natural numbers can be calculated by dividing the sum of first 15 natural ... WebThey show how you can build a cube using 3 "3D-staircases", 3 "2D-staircases", n singles and an extra single. Their formula shows that in going from a cube of size n^3 to a cube of size (n+1)^3, the larger cube is made by adding 3 face-extensions of size nxnx1, 3 new outside edges of size 1x1xn, and a new corner of size 1x1x1. how to stop calls from unknown numbers
