An empty rectangular container has a capacity of 95 ℓ and a height of 50 cm. At 8 a.m., Tap F is turned on to fill the container at a rate of 4 ℓ per minute for 19 minutes. After 7 minutes, Tap G is turned on to drain water from the container at a rate of 7 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 
4 ℓ = 4000 cm³ 
7 ℓ = 7000 cm³ 
95 ℓ = 95000 cm³

Volume of water flowed in from Tap F
= 19 x 4000
= 76000 cm³

Volume of water from drained from Tap G
= 6 x 7000
= 42000 cm³

Volume of water left in the container
= 76000 - 42000
= 34000 cm³

Base area of the container
= 95000 ÷ 50
= 1900 cm² 

Height of water left in the container
= 34000 ÷ 1900
≈ 17.9 cm

Answer(s): 17.9 cm
