To find the total volume taken up by the marbles, we can calculate the volume of a single marble and then multiply it by the total number of marbles.

Volume of one marble = 4/3 * π * r^3
Volume of one marble = 4/3 * 3.14 * 2^3
Volume of one marble = 4/3 * 3.14 * 8
Volume of one marble = 33.4933 mm^3

Total volume taken up by the marbles = 33.4933 mm^3 * 50 = 1674.665 mm^3

Unused space in the box = Total volume of the box - Total volume taken up by the marbles
Unused space in the box = 4000 mm^3 - 1674.665 mm^3
Unused space in the box = 2325.335 mm^3

Rounded to the nearest tenth, the unused space in the box is 2325.3 mm^3. Therefore, the correct answer is:
2,325.3 mm cubed.
