Earlier, I tried using this formula:

V=(a³)*100

so

V=(10³)*100

V=100000

But what I'd like to know is what is the measurement for the edge 'a'

So do I just use:

100000=x³

x= 100000^(1/3)

x=46.4

And the measurement for the edge for the new solid comprised of 100 times (cube 1) equals 46.4?

I feel like something is wrong, I haven't used any maths or geometry for ages.

Please let me know if I'm not clear enough, I can't find all the terms I need in English, it's not my native language.
