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
10 cm in a cube to find volume is 10 by 10 by 10 1000 cm cubed
10 cm is 0.1 m 0.1 times 0.1 times 0.1 is 0.001 metres cubed 19,300 times 0.001 is 19.3 kg approximately 193newtons yes it could be passed around casually
