Answer:

Hey mate here is your answer

Explanation:

Edge of the cube =4.2 cm

Let the radius of base of the cone be r cm and height be h cm.

The base of largest cone that can touch all the edges of the base of the cube and its height, is same on the edge of the cube.

Therefore,

2r=4.2cm

r=2.1cm

h=4.2cm
