volume(cm^3) = mass(g)/density(g/cm^3)
so plug in your numbers. I assume you can find the side of a cube, given its volume. (By the way, the length is cm, not cm^3!)
A cube with a mass of 40 g is made from a metal with a density of 6 g/cm3. What is the volume of the cube and the length of each edge?
----volume cm^3
-----length cm^3
