A rectangular tank measuring 65 cm by 45 cm by 28 cm was ¹₇ filled with water. Shannon turned on a tap at 3.34 p.m. to fill more water into the tank. She turned off the tap at 3.46 p.m. The tank was ⁵₇ 
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 tank at first
= ¹₇ x 65 x 45 x 28
= 11700 cm³

Volume of water in the tank in the end
= ⁵₇ x 65 x 45 x 28
= 58500 cm³

Volume of water added into the tank by the tap
= 58500 - 11700
= 46800 cm³

1000 mℓ = 1 ℓ
46800 mℓ = 46800 ÷ 1000 = 46.8 ℓ

From 3.34 p.m. to 3.46 p.m.: 12 min

Volume of water that flowed out of the tap in a minute
= 46.8 ÷ 12
= 3.9 ℓ 

Answer(s): 3.9 ℓ
