5 identical 10-cm cubes are placed in an empty rectangular container of length 72 cm and width 24 cm. The container is then filled with water from a tap flowing at a rate of 6 litres per minute. It takes 10 minutes to fill up ¹₄ 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 5 cubes
= 5 x 1000
= 5000 cm³ 

1 ℓ = 1000 mℓ
6 ℓ = 6000 mℓ

Volume of water in the container
= 10 x 6000
= 60000 mℓ

Volume of ¹₄ of the container
= 60000 + 5000
= 65000 mℓ

Volume of the container
= 65000 ÷ ¹₄
= 65000 x ⁴₁
= 260000 mℓ

Base area
= 72 x 24
= 1728 cm² 

Height of the container
= 260000 ÷ 1728
≈ 150.5 cm

Answer(s): 150.5 cm
