A cylindrical container with a radius of 3 cm and a height of 10 cm is filled with water. If this water is poured into a rectangular tank with a base of 6 cm by 5 cm, what will be the height of the water in the rectangular tank? (Use π ≈ 3.14)

A 9.42 cm
B 10.0 cm
C 8.35 cm
D 7.5 cm

✓ Correct Answer: Option A

Volume of cylinder = π * r^2 * h = 3.14 * 3^2 * 10 = 282.6 cm^3. The volume in the rectangular tank is l * w * h, so 282.6 = 6 * 5 * h. Thus, h = 282.6 / 30 = 9.42 cm.
