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
