Math Problem Statement
A person is putting oranges into a box. The dimensions of the box are 11 inches by 21 inches by 10 inches. Assuming oranges are spherical with a 2.8-inch diameter, how many oranges should fit in the box? (Hint: Packing spheres in a rectangular prism usually takes up 190% of the volume of the spheres using random packaging.)
