8 cubed means each side is 2 inches. The first box is 2 inches.
Larger shipping box has each side + 6 more inches so 2 + 6 is 12. The volume is 12 times 12 times 12 which is 1728 inches squared.
If the box with a side length of 2 can carry 1 golf ball then a box with the side length of 6 can carry 3 golf balls because 6/2 is 3. The answer for the last box is 3.
