4 identical 10-cm cubes are placed in an empty rectangular container of length 73 cm and width 21 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 ¹₃ 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 4 cubes
= 4 x 1000
= 4000 cm³ 

1 ℓ = 1000 mℓ
10 ℓ = 10000 mℓ

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

Volume of ¹₃ of the container
= 100000 + 4000
= 104000 mℓ

Volume of the container
= 104000 ÷ ¹₃
= 104000 x ³₁
= 312000 mℓ

Base area
= 73 x 21
= 1533 cm² 

Height of the container
= 312000 ÷ 1533
≈ 203.5 cm

Answer(s): 203.5 cm
