Question

Rain water, which falls on a flat rectangular surface of length 6 cm and breath 4 m is transferred into a cylindrical vessel of internal radius 10 cm. What will be the height of water in the cylindrical vessel if a rainfall of 1 cm has fallen____?

Answer 1

Given length of rectangular surface = 6 cm 

Breath of rectangular surface = 4 cm 

Height (h) 1 cm

Volume of a flat rectangular surface = lbh

Since rains are transferred to cylindrical vessel. 

So equating (1) with (2)

height of water in cylindrical vessel =190. 9 cms
