Outermost is the sphere. Inside that there is a cube and within that there is a cone and cylinder with same radius.

Here side of cube = a Diameter of Sphere = body diagnol = √3 a

Radius of sphere = √3 a/2 = r1

Height of Cylinder = Height of cone = side of cube = a = h

Radius of cylinder = Radius of cone = side of cube/2 = a/2 = r2 (as shown in the figure)
