The figure shows a rectangular container measuring 46 cm by 10 cm by 45 cm. Min poured 414 mℓ of water into the container. Then, she turned on two taps at the same time to fill up the container with water. Water was flowing from both taps at the same rate. After 12 minutes, both taps were turned off but 2.1 ℓ of water had overflowed and was collected in a tray. Find the rate of the flow of water of each tap in millilitres per minute.
Volume of the container
= 46 x 10 x 45
= 20700 cm³
= 20700 mℓ

Volume of the remaining space after water was poured in
= 20700 - 414
= 20286 mℓ 

1 ℓ = 1000 mℓ
2.1 ℓ = 2100 mℓ

Volume of water contributed by 2 taps
= 20286 + 2100
= 22386 mℓ

Volume of water contributed by 1 tap
= 22386 ÷ 2 
= 11193 mℓ 

Rate of flow per minute
= 11193 ÷ 12
= 932.75 mℓ/min

Answer(s): 932.75 mℓ/min
