The largest cone is curved out from one face of solid cube of side 21 cm. Find the volume of the remaining solid.

Answer :

Largest cone is the right circular cone with base diameter and height = edge of the cube

∴ radius of the cone = (21/2) cm

and height of the cone  =  21 cm

we know, volume of cube is (side)3

where 'r' is radius and 'h' is height of the cone.

Volume of the remaining cube = volume of the cube – volume of cone cone)
