The figure shows a rectangular container measuring 44 cm by 44 cm by 20 cm. Nora poured 194 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 7 minutes, both taps were turned off but 3.6 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
= 44 x 44 x 20
= 38720 cm³
= 38720 mℓ

Volume of the remaining space after water was poured in
= 38720 - 194
= 38526 mℓ 

1 ℓ = 1000 mℓ
3.6 ℓ = 3600 mℓ

Volume of water contributed by 2 taps
= 38526 + 3600
= 42126 mℓ

Volume of water contributed by 1 tap
= 42126 ÷ 2 
= 21063 mℓ 

Rate of flow per minute
= 21063 ÷ 7
= 3009 mℓ/min

Answer(s): 3009 mℓ/min
