An empty rectangular container has a capacity of 15 ℓ and a height of 100 cm. At 10 a.m., Tap F is turned on to fill the container at a rate of 9 ℓ per minute for 19 minutes. After 6 minutes, Tap G is turned on to drain water from the container at a rate of 8 ℓ per minute for 14 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 
9 ℓ = 9000 cm³ 
8 ℓ = 8000 cm³ 
15 ℓ = 15000 cm³

Volume of water flowed in from Tap F
= 19 x 9000
= 171000 cm³

Volume of water from drained from Tap G
= 14 x 8000
= 112000 cm³

Volume of water left in the container
= 171000 - 112000
= 59000 cm³

Base area of the container
= 15000 ÷ 100
= 150 cm² 

Height of water left in the container
= 59000 ÷ 150
≈ 393.3 cm

Answer(s): 393.3 cm
