Tank Y measuring 45 cm by 20 cm by 31 cm contains 5.9 ℓ of water. It is being filled with water flowing from Tap Z at 0.8 ℓ/min and Tap A at 668 mℓ/min. Both taps are turned on at the same time. How long does it take to fill up Tank Y till it is 58% full? Correct the answer to 1 decimal place.
Volume of Tank Y at 58% full
= 45 x 20 x 31 x 58%
= 54 x 14 x 25 x ⁷⁵₁₀₀
= 16182 cm³ 

1 ℓ = 1000 mℓ = 1000 cm³ 
5.9 ℓ = 1000 x 5.9 = 5900 cm³
0.8 ℓ = 1000 x 0.8 = 800 cm³

Volume of water to fill Tank Y
= 16182 - 5900
= 10282 cm³ 

Volume of water from the two taps per minute
= 800 + 668
= 1468 cm³/min

Time taken to fill Tank Y to 58%
= 10282 ÷ 1468
≈ 7 min

Answer(s): 7 min
