8 identical 10-cm cubes are placed in an empty rectangular container of length 78 cm and width 22 cm. The container is then filled with water from a tap flowing at a rate of 10 litres per minute. It takes 10 minutes to fill up ²₅ of the container. What is the height of the container? Correct your answer to 1 decimal place.
Volume of 1 cube
= 10 x 10 x 10
= 1000 cm³ 

Volume of 8 cubes
= 8 x 1000
= 8000 cm³ 

1 ℓ = 1000 mℓ
10 ℓ = 10000 mℓ

Volume of water in the container
= 10 x 10000
= 100000 mℓ

Volume of ²₅ of the container
= 100000 + 8000
= 108000 mℓ

Volume of the container
= 108000 ÷ ²₅
= 108000 x ⁵₂
= 270000 mℓ

Base area
= 78 x 22
= 1716 cm² 

Height of the container
= 270000 ÷ 1716
≈ 157.3 cm

Answer(s): 157.3 cm
