Answer:
2 feet.
Step-by-step explanation:
[tex]V = x^3[/tex] and [tex]V = 8[/tex]. Since both equal V, you can set them equal to each other.
[tex]x^3 = 8[/tex]
[tex]\sqrt[3]{x^3} = \sqrt[3]{8}[/tex]
[tex]x = \sqrt[3]{2^3}[/tex]
[tex]x = 2[/tex]
So, the length of an edge of the end table is 2 feet.
Hope this helps!
