ATQ, a large right circular cone is made out of cube of edge 9cm.

so the diameter and height of the cone must be the length of the edge of the cube.

therefore diameter of the cone = 9cm and also it's height is 9cm.

--> radius = 9/2cm

volume of the cone = 1/3πr²h

= 1/3 × 22/7 × 9/2 × 9/2 × 9

= 11/7 × 3 × 9/2 × 9

= 2673/14cm³

and volume of the cube = side³

= 9 × 9 × 9

= 729cm³

therefore volume of remaining part of solid = 729 - 2673/14

= (10206 - 2673)/14

= 7533/14

= 538.07cm³ (approximately)
