How many spherical balls of radius 5 cm can be made by melting a spherical clay ball having a radius of 15 cm?
Explanation:
Let 'n' spherical balls can be made.
∴ Volume of n spherical balls = Volume of the original clay ball
⇒ 4/3 × π × 53 × n = 4/3 × π × 153
⇒ 53 × n = 153
⇒ n = 33
⇒ n = 27
Hence, option (b).
