5 identical 6-cm cubes are placed in an empty rectangular container of length 79 cm and width 24 cm. The container is then filled with water from a tap flowing at a rate of 7 litres per minute. It takes 13 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
= 6 x 6 x 6
= 216 cm³ 

Volume of 5 cubes
= 5 x 216
= 1080 cm³ 

1 ℓ = 1000 mℓ
7 ℓ = 7000 mℓ

Volume of water in the container
= 13 x 7000
= 91000 mℓ

Volume of ¹₂ of the container
= 91000 + 1080
= 92080 mℓ

Volume of the container
= 92080 ÷ ¹₂
= 92080 x ²₁
= 184160 mℓ

Base area
= 79 x 24
= 1896 cm² 

Height of the container
= 184160 ÷ 1896
≈ 97.1 cm

Answer(s): 97.1 cm
