A rectangular container measuring 70 cm by 60 cm by 24 cm was ¹₃ filled with water. Gillian turned on a tap at 9.28 p.m. to fill more water into the container. She turned off the tap at 9.44 p.m. The container was ²₃ 
filled with water. Given that the water flowed out of the tap at the same rate, find the volume of water that flowed out of the tap in a minute. Give your answer in litres.
Volume of water in the container at first
= ¹₃ x 70 x 60 x 24
= 33600 cm³

Volume of water in the container in the end
= ²₃ x 70 x 60 x 24
= 67200 cm³

Volume of water added into the container by the tap
= 67200 - 33600
= 33600 cm³

1000 mℓ = 1 ℓ
33600 mℓ = 33600 ÷ 1000 = 33.6 ℓ

From 9.28 p.m. to 9.44 p.m.: 16 min

Volume of water that flowed out of the tap in a minute
= 33.6 ÷ 16
= 2.1 ℓ 

Answer(s): 2.1 ℓ
