Question

Calculate the density (d) of a spherical meteoroid having a diameter of 15m and a mass of 6 × 109kg. Express the result in g/cm3.

Answer 1

Volume of a sphere: V = 4/3πr3

Radius r = 7.5 m = 750 cm

V = 4/3 x 3.14 x (750)3 = 17.66 x 108cm3

Density d = (6 x 109 x 103)/(17.66 x 108) = 3.39g/cm3
