Answer:
A.
If the depth is 8 feet, the area of the base is 300 square feet. And if the area of the base is 600 square feet, the depth of the water is 4 feet.
Step-by-step explanation:
Depth = Volume/Area
d = V/A
12 = V/200
V = 12 × 200
= 2,400
When d = 8, A = 300
V = dA
= 8 × 300
= 2,400
When d = 4, A = 600
V = 4 × 600
= 2,400.
The first option is correct.
