Solution:

Let’s analyze each answer choice.

A) Since 12/2.5 = 4.8, the dimensions in choice A can only hold 4.8 reams of paper.

B) Since 17/8.5 = 2, 15/2.5 = 6 and 2 x 6 = 12, the dimensions in choice B can hold 12 reams of paper. To fill the carton, then, two reams will be placed side-by-side in the bottom and then 5 reams will be stacked on top of each.of the two reams, making 2 stacks of 6 reams each.

Answer: B
