An empty rectangular container has a capacity of 161 ℓ and a height of 175 cm. At 9 a.m., Tap A is turned on to fill the container at a rate of 5 ℓ per minute for 16 minutes. After 8 minutes, Tap B is turned on to drain water from the container at a rate of 6 ℓ per minute for 6 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 
6 ℓ = 6000 cm³ 
161 ℓ = 161000 cm³

Volume of water flowed in from Tap A
= 16 x 5000
= 80000 cm³

Volume of water from drained from Tap B
= 6 x 6000
= 36000 cm³

Volume of water left in the container
= 80000 - 36000
= 44000 cm³

Base area of the container
= 161000 ÷ 175
= 920 cm² 

Height of water left in the container
= 44000 ÷ 920
≈ 47.8 cm

Answer(s): 47.8 cm
