The area of the base = the area of the middle rectangle plus  twice the area of the flanking right triangles.......so we have....

 

4 * 3   +   2 [  2 * 3] / 2  =

 

12 + 6   =

 

18 sq cm

 

And the volume of the cone  [ actually, a pyramid ]  =

 

(Area  of the base) * ( Height)  / 3

 

(18 cm^2) ( 6 cm)  / 3  =

 

108cm^3 / 3  =

 

36 cm^3
