6 identical 6-cm cubes are placed in an empty rectangular container of length 79 cm and width 29 cm. The container is then filled with water from a tap flowing at a rate of 10 litres per minute. It takes 14 minutes to fill up ²₅ 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 6 cubes
= 6 x 216
= 1296 cm³ 

1 ℓ = 1000 mℓ
10 ℓ = 10000 mℓ

Volume of water in the container
= 14 x 10000
= 140000 mℓ

Volume of ²₅ of the container
= 140000 + 1296
= 141296 mℓ

Volume of the container
= 141296 ÷ ²₅
= 141296 x ⁵₂
= 353240 mℓ

Base area
= 79 x 29
= 2291 cm² 

Height of the container
= 353240 ÷ 2291
≈ 154.2 cm

Answer(s): 154.2 cm
