Given:
length of rectangular surface=L= 6m=6×100=600cm
Breadth of rectangular surface=B=4m=400cm
Height of water in rectangular surface =H=1cm
radius of cylindrical vessel=20cm
Height of water in cylindrical vessel=h
According to given:
Volume of rectangular surface = Volume of cylindrical vessel
LxBxH = pi r^2 h
600x400x1=22/7 ×20×20×h
h= 600x400x7/22×20×20
=4200/22.
=190.90cm
The height of water in the cylindrical vessel if the rainfall is 1cm is 190.90cm
