"Taking a cube" is the same basic procedure, whether it's a one-digit number, a three digit number, a complex number, a square matrix, or anything else you can multiply. Taking the cube simply means, multiply the number by itself, in such a way that it appears three times as a factor. For example, if your three-digit number is 235, you calculate the cube as 235 x 235 x 235.

That number times itself twice. Ex. 4^3= 4•4•4= 64

It doesn't matter if you know that the largest three-digit prime number is 997 or that its cube root is 9.98998998. If you include zero in the whole numbers, the answer will be zero.

On a single roll, three out of the six possible outcomes are even numbers = 50%.

I am pretty sure you can figure this out on your own. Raise different numbers to the square, until you get a 4-digit result. Similary, calculate the cube of different numbers, until you get a 4-digit number. If you want the SAME number to be both a perfect square and a perfect cube, then it must be a power of 6. In that case, just experiment raising different numbers to the sixth power, until you get a 4-digit number.

It is 1 multiplied by the number three times and is called a perfect cube.
