Volume of water in the pot = 1 u
Volume of water in the container = 1 u + 3.3
Total volume of water
= 1 u + 1 u + 3.3
= 2 u + 3.3
Total volume of water
= 2 x 4
= 8 ℓ
When water is poured from the container to the pot, the total volume remains unchanged.
2 u + 3.3 = 8
2 u = 8 - 3.3
2 u = 4.7
1 u = 4.7 ÷ 2 = 2.35
Volume of water in the pot at first = 2.35 ℓ
Answer(s): 2.35 ℓ
