Answer:
35.8 meters
Explanation:
Let x be the lake depth. We are given the lake volume and its surface area. We know that the area times the depth is equal to the total volume:
(Depth)*(Area), or x*Area =Volume
We are given the area and volume, so we can write:
x*(69604 km^2) = 2560 km^3
x = 0.036779 km
We can convert this to meters (from km):
x = 35.8 meters
