An action movie production team needs glass spheres to hold a green liquid that looks like an explosive l. if all of the available 3,392'92 cubic inches of the liquid is to be poured into 30 glass spheres l, what should the diameter of each sphere be. assume that each sphere is filled to the top

We need 30 glass spheres whose TOTAL volume = 3,392.92 cubic inches.
Therefore each of the 30 spheres must have a volume of  3,392.92 / 30 =
113.0973333333 cubic inches
Sphere Volume   =   4/3 • π • r³
radius^3 = Sphere Volume / (4/3 • π)
radius^3 = 113.0973333333 / 4.1887902048
radius^3 = 26.9999994758
radius = 3 inches
diameter = 6 inches
