Answer:
 D)  1,036,800 boxes
Step-by-step explanation:
The volume of a box is ...
 (20 in)(18 in)(15 in) = 5400 in^3
The volume of the storage space is ...
 (300 ft)(240 ft)(45 ft) = 3,240,000 ft^3
Then the number of boxes that will fit in the storage space is ...
 (3240000 ft^3)(1728 in^3/ft^3)/(5400 in^3/box) = 1,036,800 boxes
