An empty rectangular container has a capacity of 111 ℓ and a height of 25 cm. At 6 a.m., Tap E is turned on to fill the container at a rate of 10 ℓ per minute for 16 minutes. After 14 minutes, Tap F is turned on to drain water from the container at a rate of 2 ℓ per minute for 11 minutes. What is the height of the water level in the container in the end? Give the answer in 1 decimal place.
1 ℓ = 1000 cm³ 
10 ℓ = 10000 cm³ 
2 ℓ = 2000 cm³ 
111 ℓ = 111000 cm³

Volume of water flowed in from Tap E
= 16 x 10000
= 160000 cm³

Volume of water from drained from Tap F
= 11 x 2000
= 22000 cm³

Volume of water left in the container
= 160000 - 22000
= 138000 cm³

Base area of the container
= 111000 ÷ 25
= 4440 cm² 

Height of water left in the container
= 138000 ÷ 4440
≈ 31.1 cm

Answer(s): 31.1 cm
