A rectangular tank measuring 75 cm by 60 cm by 32 cm was ¹₁₀ filled with water. Shannon turned on a tap at 8.26 p.m. to fill more water into the tank. She turned off the tap at 8.38 p.m. The tank was ⁵₆ 
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
= ¹₁₀ x 75 x 60 x 32
= 14400 cm³

Volume of water in the tank in the end
= ⁵₆ x 75 x 60 x 32
= 120000 cm³

Volume of water added into the tank by the tap
= 120000 - 14400
= 105600 cm³

1000 mℓ = 1 ℓ
105600 mℓ = 105600 ÷ 1000 = 105.6 ℓ

From 8.26 p.m. to 8.38 p.m.: 12 min

Volume of water that flowed out of the tap in a minute
= 105.6 ÷ 12
= 8.8 ℓ 

Answer(s): 8.8 ℓ
