3/5 to rectangular tank
2/5 to cylinderical tank

volume of tanker = pi r^2 H = pi d^2/4 h
= pi (4/4)(4.2) = 13.2 m^3

(3/5 )13.2 = 7.92 m^3 = 3.96 h
so h = 2 meters

(2/5 )13.2 = 5.28 m^3
5.28 = pi (4/4) h
h = 1.68 meter

vol of cylinder=pie*r^2*h
(22/7)*1^2*4.2=13.2
rectangula booth==>3 of 5 parts
(3/5)*13.2=7.92m
cyliderical booth recives 13.2-7.92=5.28m
