Answer:

4.5 m

Explanation:

Shallow excavations are defined as being anything less than 1.5 meters deep, which really is not very deep at all; a relatively short person could comfortably see over the top. Deep excavations, on the other hand, are defined as being any excavation that is more than 4.5 meters in depth – a considerable height indeed
