To find the depth (aka "height") you must use the volume formula
Volume = length x width x height
In this case:
The amount of water the pool can contain will equal to the volume
Volume = 1,472 m
length = 36.8 m
width = 20 m
height = unknown (let's make this h)
^^^Plug these numbers into the formula given above
1,472 = 36.8 x 20 x h
1,472 = 736h
Isolate h by dividing 736 to both sides
1,472/736 = 736h/736
2
This pool is 2 meters deep
Hope this helped!
