In one scene in the movie The Godfather II,
a solid gold phone is passed around a large
table for everyone to see. Suppose the volume
of gold in the phone were equal to the volume
of a 10-centimeter cube of gold. The density
of gold is 19,300 kg/m3
.
Could such a phone be casually passed
around a table from hand to hand? What
is the weight of the phone? 1 kg of mass is
about 2.2 lb
