Answer 2

Answer:512 balls

Step-by-step explanation:

volume of spherical lead=4/3 pie r^3

                                        =4/4*pie*8*8*8

volume of ball=4/3 pie r^3

                        = 4/3 *pie*1*1*1

therefore

let n be the number of balls

hence,

=>4/3*pie*n=4/3*pie*8*8*8

=> n= 512
