Therefore the ratio of the side of cube to the radius of the new sphere is
Step-by-step explanation:
Given that a sphere is melted and half of the melted liquid is used to form 11 identical cubes and remaining half is used to form of 7 identical smaller sphere.
Then
The volume of 11 cubes = The volume of 7 smaller sphere.
Consider the length of side of the square be x.
Consider the length of radius of the spheres be y.
The volume of a square is = side³
the volume one sphere is =
The volume of 11 cubes =( 11×x³) cubic unit
The volume of 7 spheres = cubic unit
According to the problem,
Therefore the ratio of the side of cube to the radius of the new sphere is
