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.
A number can't be cubed and prime. Cubed numbers (other than 1) have more than two factors.
Cubed is the third dimension because it is a cube. A cube has three dimensions of equal amount. A cube of three-inch sides, to get its volume you'd multiply three times three times three, which is three cubed.

The first 5 cubed numbers are 1x1x1=1, 2x2x2=8, 3x3x3=27, 4x4x4=64 and 5x5x5=125. :)
Well, honey, the cubed numbers between 2000 and 3000 are 8 cubed (512), 9 cubed (729), 10 cubed (1000), 11 cubed (1331), 12 cubed (1728), 13 cubed (2197), 14 cubed (2744), and 15 cubed (3375). So, there you have it, sweetie!
1, 8, 27, 64
A number can't be cubed and prime. Cubed numbers (other than 1) have more than two factors.
Three cubed is 27
the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.
The first three prime numbers are 2,3 and 5.
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
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.
1.3 cubed is equal to 2.197
