How many spherical balls of radius 5 cm can be made by melting a spherical clay ball having a radius of 15 cm?

18 3 9 27

27

Given, Radius of spherical clay ball = 15 cm Radius of smaller clay balls = 5 cm So, the spherical balls that can be made = \(\frac{15^3}{5^3}\) = \(\frac{3375}{125}\) = 27
