Answer:
301.44 cubic units
Step-by-step explanation:

So every 5 inches in height, there are 32 marbles. You want to know how many marbles there are per 18 inches in height.

To get from 5 to 18, you multiply by 3.6.
Do the same thing to the numerator; 32 × 3.6 = 115.2.
Since 0.2 marbles is no marbles, you round down.
There are 115 marbles in the box.
