An empty rectangular container has a capacity of 64 ℓ and a height of 160 cm. At 10 a.m., Tap R is turned on to fill the container at a rate of 8 ℓ per minute for 19 minutes. After 14 minutes, Tap S is turned on to drain water from the container at a rate of 3 ℓ per minute for 11 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 
64 ℓ = 64000 cm³

Volume of water flowed in from Tap R
= 19 x 8000
= 152000 cm³

Volume of water from drained from Tap S
= 11 x 3000
= 33000 cm³

Volume of water left in the container
= 152000 - 33000
= 119000 cm³

Base area of the container
= 64000 ÷ 160
= 400 cm² 

Height of water left in the container
= 119000 ÷ 400
≈ 297.5 cm

Answer(s): 297.5 cm
