Volume of that fall on the roof
= 60 × 40 × (0.08 )
= 192 m^3
volume of tank water=volume of fall water on the roof
=> π × (3.5)^2 × h = 192
=> π × 12.25 × h = 192
=> h = 192/π×12.25
=> h = 192/(22÷7)×12.25
=> h = 192/38.5
=> h = 4.98 = 5m (approx)
= 60 × 40 × (0.08 )
= 192 m^3

Answer:
Length of rectangular surface (L) = 6 m = 600 cm
Breadth of rectangular surface (B) = 4 m = 400 cm
Height of rectangular surface (H) = 1 cm
Radius of cylindrical vessel (r) = 20 cm
Let the height of cylindrical vessel = h cm
Volume of rectangular surface = Volume of cylindrical vessel
⇒ L

⇒ h = 190.90 cm
∴ Height of the cylindrical vessel is 190.90 cm.
