Step-by-step explanation:

radii of big sphere (R)= 10 cm

Vol. of sphere =

4/3 × 22/7× 10×10×10

now

radii of resulting sphere(r) = 2 cm

Vol. of resulting sphere = 4/3×22/7 × 2×2×2

let n be the no. of sphere

therefore n = vol. of first sphere

Vol of resulting sphere

= 4/3×22/7×10×10×10

4/3×22/7× 2×2×2

=> 5×5×5

=> 125

no. of sphere formed are => 125
