An empty rectangular container has a capacity of 41 ℓ and a height of 40 cm. At 9 a.m., Tap Z is turned on to fill the container at a rate of 8 ℓ per minute for 17 minutes. After 2 minutes, Tap A is turned on to drain water from the container at a rate of 8 ℓ per minute for 5 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 
8 ℓ = 8000 cm³ 
8 ℓ = 8000 cm³ 
41 ℓ = 41000 cm³

Volume of water flowed in from Tap Z
= 17 x 8000
= 136000 cm³

Volume of water from drained from Tap A
= 5 x 8000
= 40000 cm³

Volume of water left in the container
= 136000 - 40000
= 96000 cm³

Base area of the container
= 41000 ÷ 40
= 1025 cm² 

Height of water left in the container
= 96000 ÷ 1025
≈ 93.7 cm

Answer(s): 93.7 cm
