Answer:
525 truckloads
Explanation:
First we need to find the volume of the pool. This lets us know how much dirt must be moved.
25*19*5 = 2,375 cubic feet total.
Divide that by 4.53 cubic feet for each load, and we get 524.282 truckloads. Round up to the nearest integer for a final answer of 525 truckloads.
