8 identical 8-cm cubes are placed in an empty rectangular container of length 78 cm and width 22 cm. The container is then filled with water from a tap flowing at a rate of 8 litres per minute. It takes 8 minutes to fill up ¹₅ of the container. What is the height of the container? Correct your answer to 1 decimal place.
Volume of 1 cube
= 8 x 8 x 8
= 512 cm³ 

Volume of 8 cubes
= 8 x 512
= 4096 cm³ 

1 ℓ = 1000 mℓ
8 ℓ = 8000 mℓ

Volume of water in the container
= 8 x 8000
= 64000 mℓ

Volume of ¹₅ of the container
= 64000 + 4096
= 68096 mℓ

Volume of the container
= 68096 ÷ ¹₅
= 68096 x ⁵₁
= 340480 mℓ

Base area
= 78 x 22
= 1716 cm² 

Height of the container
= 340480 ÷ 1716
≈ 198.4 cm

Answer(s): 198.4 cm
