Answer:
4 trucks
Explanation:
Here, we are told that 5 trucks carry a load of 20 m^3 each
This means that the total amount of load is 5 * 20 = 100 m^3
Now, we are having this load carried by a number of trucks with each carrying 25 m^3
The number of trucks that would carry the load would be 100 m^3/25 m^3 = 4
