Difference in the volume of water between the tank and the pail
= 16.4 - 1.7
= 14.7 ℓ
Since Rael poured in an equal volume of water into each container, the difference in the volume of water at first and in the end remains the same.
3 u = 14.7
1 u = 14.7 ÷ 3 = 4.9
Volume of water that Rael poured into each container
= 1 u - 1.7
= 4.9 - 1.7
= 3.2 ℓ
Answer(s): 3.2 ℓ
