2. A person just purchased a vending machine with
three compartments. Each compartment has the
dimensions of 6 inches by 8 inches by 18 inches,
Assuming the vending machine uses gumballs that
are approximately spherical and 2 inches in diameter,
how many gurnballs should fit in one of the
compartments?
(Hint: Packing spheres in a rectangular prism usually
take up 190% of the volume of spheres.)
