How many spherical balls of radius 2 cm can be made out of a solid cube of lead whose side measures 44 cm?

Answer :


Given.


Radius of sphere is 2 cm


Side of cube is 44 cm


Formula used/Theory.


Volume of sphere = πr3


Volume of cube = side3


Volume of sphere = πr3


= × (2 cm)3


Volume of cube = side3


= (44 cm)3


Number of spherical balls will be get by dividing Volume of cube by Volume of each Sphere


Number of spheres =


=


=


= 2541
