Answer:
The side length of the cube is 9.
Step-by-step explanation:
To find the volume of a cube you use the equation V=E³, although edge can mean length.
Since we already know the volume though, we have to do this equation backwards, and find the cubed root of 729.
To do this we do [tex]\sqrt[3]{729\\}[/tex] which will give us our answer of 9 cubic inches.
Hope this helped!
