Answer:
15.9
Step-by-step explanation:
Since the volume of a cube is equal to length*width*height, and we know that in this case length, width, and height are all equal, since it is a cube, all you need to do is create an equation like this:
4019.679 = x^3
x is the side length.
15.9*15.9*15.9, 15.9^3.
