Answer:
dv = surface area * dh
so
dv/dt = surface area * dh/dt
width at surface = 40 + (80-40)(30/40)
= 40 + 30 = 70 cm = 0.70 m
so
surface area = 9 * .7 = 6.3 m^2
so
.3 m^3/min = 6.3 m^2 * dh/dt
and
dh/dt = .047 meters/min or 4.7 cm/min

I believe your answer is:
31.69

Here’s why:
⸻⸻⸻⸻
- '9' is in the hundredths place. The rounding is the digit to it's right, or '3'.
- Since 3 is less than or equal to 4, we would round down.

31.693 ≈ 31.69
