A 3 cm-radius solid metal sphere is melted and reshaped into smaller spheres, each with a 1 cm radius. From the original sphere, how many smaller spheres can be created?
Show answer & explanation
Correct answer: C
Explanation
Radius of the large sphere = 3 cm, Radius of the small sphere = 1 cm
Volume = r³
Number of small spheres = (3³) / (1³)
= 27 / 1
= 27
