An empty rectangular container has a capacity of 38 ℓ and a height of 125 cm. At 9 a.m., Tap T is turned on to fill the container at a rate of 7 ℓ per minute for 17 minutes. After 3 minutes, Tap U is turned on to drain water from the container at a rate of 2 ℓ per minute for 25 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 
7 ℓ = 7000 cm³ 
2 ℓ = 2000 cm³ 
38 ℓ = 38000 cm³

Volume of water flowed in from Tap T
= 17 x 7000
= 119000 cm³

Volume of water from drained from Tap U
= 25 x 2000
= 50000 cm³

Volume of water left in the container
= 119000 - 50000
= 69000 cm³

Base area of the container
= 38000 ÷ 125
= 304 cm² 

Height of water left in the container
= 69000 ÷ 304
≈ 227 cm

Answer(s): 227 cm
