➵ Combination of a solid is that figure which is formed by combining two or more different solids. As new solids are formed, the surfaces tend to overlap and hence, some of the surfaces are eliminated.

➵ Some examples of combination of solids are:-

• A circus tent is a combination of a cylinder and a cone.
• An ice cream cone is a combination of a cone and a hemisphere.
