If the volume of a cube is 343x^12, what is its side length.

I’m trying to find out how to set the formula up, not for answers.
Thank you!

volume =- 343E12 what? what unit?
volume = (length)^3
343E12 =(length)^3
length = (343E12)^1/3.
for a cube , side^3 = volume
so side = (343x^12) = 7x^4
Thanks!
