volume of cylinder = pi r2h
(22/7) * 12* 3.5 = 11 m3
given the top of the roof is rectangle in shape
let us assume the drain is closed first.due to rainfall it fills the rectangle to a height h cm
ie., if we take it to a cuboid
then the volume of water filled in cylinder = volume of cuboid
l b h = 11 m3
22 * 20 * h= 11
h = 2.5 cm
(22/7) * 12* 3.5 = 11 m3

but I think water is kept in cuboid shape
I think not
