An empty rectangular container has a capacity of 58 ℓ and a height of 200 cm. At 10 a.m., Tap S is turned on to fill the container at a rate of 5 ℓ per minute for 17 minutes. After 12 minutes, Tap T is turned on to drain water from the container at a rate of 2 ℓ per minute for 27 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 
5 ℓ = 5000 cm³ 
2 ℓ = 2000 cm³ 
58 ℓ = 58000 cm³

Volume of water flowed in from Tap S
= 17 x 5000
= 85000 cm³

Volume of water from drained from Tap T
= 27 x 2000
= 54000 cm³

Volume of water left in the container
= 85000 - 54000
= 31000 cm³

Base area of the container
= 58000 ÷ 200
= 290 cm² 

Height of water left in the container
= 31000 ÷ 290
≈ 106.9 cm

Answer(s): 106.9 cm
