Step-by-step explanation:
The dimensions of the box = 4.9 by 6.5 by 5.6
We would the dimensions to find the volume of the rectangular box:

radius of gumball = 1/2 in = 0.5 in
gumball are spherical in shape, so we find the volume of the gumball:

Packing density of spheres = 5/8
This means 5/8 of the rectangular box will contain the gumballs while the rest will be air

Number of gumballs needed:
