17 answer plz i need it

Answer 1

we know , volume of sphere is 4/3 πr cube
ATQ, no. of spherical balls x volume = volume of sphere,

let no. of balls = n
radius of each ball = 0.6/3 = 0.3 cm

so,. n x 4/3 πr cube = 4/3 π R cube

so, 4/3 x 3.14 x 3 x 3 x 3 = n x 4/3 x 3.14 x 0.3 x 0.3 x 0.3

n = 3 cube / 0.3 cube
= 27/0.027

n = 1000
