AI explanation

The volume of rainwater is the rectangular surface area times the rainfall depth, which equals 600 cm times 400 cm times 1 cm, giving 240,000 cubic cm. This volume transfers into the cylindrical vessel, so using the cylinder volume formula, 240,000 equals pi times 120 squared times the height. Solving for the height gives 240,000 divided by (3.14 times 14,400), which results in 190.9 cm.
