An empty rectangular container has a capacity of 58 ℓ and a height of 25 cm. At 8 a.m., Tap Y is turned on to fill the container at a rate of 10 ℓ per minute for 19 minutes. After 9 minutes, Tap Z is turned on to drain water from the container at a rate of 3 ℓ per minute for 30 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 
3 ℓ = 3000 cm³ 
58 ℓ = 58000 cm³

Volume of water flowed in from Tap Y
= 19 x 10000
= 190000 cm³

Volume of water from drained from Tap Z
= 30 x 3000
= 90000 cm³

Volume of water left in the container
= 190000 - 90000
= 100000 cm³

Base area of the container
= 58000 ÷ 25
= 2320 cm² 

Height of water left in the container
= 100000 ÷ 2320
≈ 43.1 cm

Answer(s): 43.1 cm
