A cubed number has been multiplied by itself 3 times, so x cubed is x times x times x.
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!
Use the definition of "cubed". 7 billion cubed is the same as 7 billion x 7 billion x 7 billion.
8 is 2 cubed 27 is 3 cubed
The first 5 cubed numbers are 1x1x1=1, 2x2x2=8, 3x3x3=27, 4x4x4=64 and 5x5x5=125. :)
216 & 343
A number can't be cubed and prime. Cubed numbers (other than 1) have more than two factors.

The sum of the first n cubed numbers is the square of the nth triangular number.
Yes. For example 3 is the cube of cuberoot(3). However, by definition, a prime number cannot be a PERFECT cube.
Numbers multiplied by it's self 3 times
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.
2,628,071 and 2,628,073. 138 cubed is 2,628,072
Perfect cubes.
Use the definition of "cubed". 7 billion cubed is the same as 7 billion x 7 billion x 7 billion.
