An empty rectangular container has a capacity of 84 ℓ and a height of 80 cm. At 6 a.m., Tap S is turned on to fill the container at a rate of 8 ℓ per minute for 16 minutes. After 8 minutes, Tap T is turned on to drain water from the container at a rate of 3 ℓ per minute for 23 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 
3 ℓ = 3000 cm³ 
84 ℓ = 84000 cm³

Volume of water flowed in from Tap S
= 16 x 8000
= 128000 cm³

Volume of water from drained from Tap T
= 23 x 3000
= 69000 cm³

Volume of water left in the container
= 128000 - 69000
= 59000 cm³

Base area of the container
= 84000 ÷ 80
= 1050 cm² 

Height of water left in the container
= 59000 ÷ 1050
≈ 56.2 cm

Answer(s): 56.2 cm
