A rectangular container measuring 80 cm by 65 cm by 35 cm was ¹₇ filled with water. Ivory turned on a tap at 6.34 p.m. to fill more water into the container. She turned off the tap at 6.59 p.m. The container was ⁶₇ 
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
= ¹₇ x 80 x 65 x 35
= 26000 cm³

Volume of water in the container in the end
= ⁶₇ x 80 x 65 x 35
= 156000 cm³

Volume of water added into the container by the tap
= 156000 - 26000
= 130000 cm³

1000 mℓ = 1 ℓ
130000 mℓ = 130000 ÷ 1000 = 130 ℓ

From 6.34 p.m. to 6.59 p.m.: 25 min

Volume of water that flowed out of the tap in a minute
= 130 ÷ 25
= 5.2 ℓ 

Answer(s): 5.2 ℓ
