5 identical 3-cm cubes are placed in an empty rectangular container of length 76 cm and width 25 cm. The container is then filled with water from a tap flowing at a rate of 9 litres per minute. It takes 10 minutes to fill up ¹₂ of the container. What is the height of the container? Correct your answer to 1 decimal place.
Volume of 1 cube
= 3 x 3 x 3
= 27 cm³ 

Volume of 5 cubes
= 5 x 27
= 135 cm³ 

1 ℓ = 1000 mℓ
9 ℓ = 9000 mℓ

Volume of water in the container
= 10 x 9000
= 90000 mℓ

Volume of ¹₂ of the container
= 90000 + 135
= 90135 mℓ

Volume of the container
= 90135 ÷ ¹₂
= 90135 x ²₁
= 180270 mℓ

Base area
= 76 x 25
= 1900 cm² 

Height of the container
= 180270 ÷ 1900
≈ 94.9 cm

Answer(s): 94.9 cm
