Metallic spheres of radii 6 cm, 8 cm and 10 cm, respectively, are melted to form a single solid sphere. Find the radius of the resulting sphere.

**Solution:**

Radius of first Sphere **cm**

Radius of second Sphere **cm**

Radius of third Sphere **cm**

Let radius of resulting sphere **cm**

**According to given condition, we have**

Volume of First Sphere + Volume of 2nd Sphere + Volume of 3rd Sphere = Volume of Resulting Sphere

**cm**
