6 identical 10-cm cubes are placed in an empty rectangular container of length 84 cm and width 25 cm. The container is then filled with water from a tap flowing at a rate of 6 litres per minute. It takes 12 minutes to fill up ³₄ 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 6 cubes
= 6 x 1000
= 6000 cm³ 

1 ℓ = 1000 mℓ
6 ℓ = 6000 mℓ

Volume of water in the container
= 12 x 6000
= 72000 mℓ

Volume of ³₄ of the container
= 72000 + 6000
= 78000 mℓ

Volume of the container
= 78000 ÷ ³₄
= 78000 x ⁴₃
= 104000 mℓ

Base area
= 84 x 25
= 2100 cm² 

Height of the container
= 104000 ÷ 2100
≈ 49.5 cm

Answer(s): 49.5 cm
