a warehouse is used as a granary. is is the shape of a cuboid surmounted by a half-cylinder. the base of the shed is 6m x 14m and its height is 8m. find the surface area of the non-cubiodal part.

Diameter of the half cylinder = 6 m
Radius of the half cylinder = 6 m2= 3m
Height of the half cylinder = 14 m
Total surface area of the non-cuboidal part = surface area of two semicircle+curved surface area of half cylinderTotal surface area=2×12πr2+12×2πrh =πr2+πrh=πr(r+h)=227×3m×17m=160.28 m2
