Answer:
10ft
Step-by-step explanation:
The length of one side of this cube would be the cube root of 1000 since each of the three dimensions are the same. You could solve this problem with the following equation, where [tex]l[/tex] is the side length.
[tex]l^3[/tex] = 1000
[tex]l[/tex] = [tex]\sqrt[3]{1000}[/tex]
[tex]l[/tex] = 10
So, the side length of the edge of the cube is 10ft.
