4 identical 8-cm cubes are placed in an empty rectangular container of length 74 cm and width 25 cm. The container is then filled with water from a tap flowing at a rate of 8 litres per minute. It takes 8 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
= 8 x 8 x 8
= 512 cm³ 

Volume of 4 cubes
= 4 x 512
= 2048 cm³ 

1 ℓ = 1000 mℓ
8 ℓ = 8000 mℓ

Volume of water in the container
= 8 x 8000
= 64000 mℓ

Volume of ²₅ of the container
= 64000 + 2048
= 66048 mℓ

Volume of the container
= 66048 ÷ ²₅
= 66048 x ⁵₂
= 165120 mℓ

Base area
= 74 x 25
= 1850 cm² 

Height of the container
= 165120 ÷ 1850
≈ 89.3 cm

Answer(s): 89.3 cm
