Question

Q.2. A spherical ball of diameter 21 cm is melted and recasted into cubes, each of side 1 cm. Find
the number of cubes thus formed. ​

Answer 1

diameter of spherical ball is 21cm

edges of each cube is 1cm

volume of spherical ball = 4/3 πr³

so ,

ATQ

volume of spherical ball= 4/3 π* (21/2)³

volume of each cube= 1³= 1cm³

4/3*22/7*21/2*21/2*21/2=n *1

where n is the total no. of cubes.

therefore,

n= above one .

calculate it.

hope it helps
