Step-by-step explanation:

To solve this exercise, we must resort to a proportion rule.

Knowing what happened in the first place, how much was needed, a direct proportion will be made with the other accident, be as follows.

Landslide                                     Dump Truck Loads

3 yd ^ 3 -------------------------------------------> 200

40 yd ^ 3 -------------------------------------------> X

X = (40 * 200) / 3

X = 2666.6, that is, for 40 cubic yards of sliding, approximately 2667 dump truck loads are needed.
