A rectangular container measuring 65 cm by 60 cm by 24 cm was ¹₄ filled with water. Gabby turned on a tap at 7.31 p.m. to fill more water into the container. She turned off the tap at 7.44 p.m. The container was ⁷₈ 
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
= ¹₄ x 65 x 60 x 24
= 23400 cm³

Volume of water in the container in the end
= ⁷₈ x 65 x 60 x 24
= 81900 cm³

Volume of water added into the container by the tap
= 81900 - 23400
= 58500 cm³

1000 mℓ = 1 ℓ
58500 mℓ = 58500 ÷ 1000 = 58.5 ℓ

From 7.31 p.m. to 7.44 p.m.: 13 min

Volume of water that flowed out of the tap in a minute
= 58.5 ÷ 13
= 4.5 ℓ 

Answer(s): 4.5 ℓ
