To find the diameter of the new solid ball formed by melting three smaller balls of iron with diameters of 6 cm, 8 cm, and 10 cm, we can follow these steps: ### Step 1: Calculate the radii of the three balls. - The radius is half of the diameter. - For the first ball (diameter = 6 cm): \[ r_1 = \frac{6}{2} = 3 \text{ cm} \] ...
