Answer: 562500 m²
Step-by-step explanation:
Depth = 1.5m
Width = 6m
Height of standing water = 0.08m in 30 minutes
Length of water column = 5km = 5000m
Volume of water in 30 minutes = 1.5 * 6 * 5000 = 45000m cube
Area = VOLUME / HEIGHT
= 45000/0.08
= 562500m²..........solution........
Hope you understood
