Answer 2

Answer:

1000 balls

Step-by-step explanation:

Let the radius of solid sphere be R = 3cm and the smaller spheres which are recasted  be radius r = 0.3 cm.

According to question,

Solid sphere is recasted into many smaller spheres,i.e. Volume is unchanged and thus Both have same volume.

   ∴             $\frac{4}{3}$$\pi$$R^{3}$=     $\frac{4}{3}$$\pi$$r^{3}$× n

                       ⇒         $3^{3}$ = $0.3^{3}$× n

                       ⇒      n =1000 balls
