We have that the volume of a cube with side lengths s is:
[tex]V=s\cdot s\cdot s=s^3[/tex]siince in this case, the volume is 8 cubic meters, we have:
[tex]s^3=8^{}[/tex]notice that the prime factorization of 8 is:
[tex]8=2\cdot2\cdot2[/tex]therefore, we have that the length of one edge of the cube is 2 m
