Given: The edge of cube = 9 cm 

⇒This will be the altitude of the cone. 

Now,

The radius of circular cone will be 9/2=4.5 cm. 

As, we know that,
The volume of cone is given by formula: 

where,

R is the radius and H the altitude of cone. 

Also, we are asked for the largest cone, its volume must be equal or less than the volume of cube...
