what do u mean by the perimeter of a 3D shape?
well, if it means sum of length of edges, then it is:-
cube-12*a
cuboid-4*(l+b+h)
cylinder-4πr
cone-2πr
sphere-0
hemisphere-2πr

1.cube=6 × side2

2.cuboid = 4(L+B+H)

3.cylinder =pi × radius2 × height

4.cone= (1/3) × pi × radius2 × height

5.sphere=(4/3) × pi × radius3

6.hemisphere = 3(pi)R^2.
