Question

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.. . 1. Yes; it weighs about 9 lbs. . 2. No; it weighs about 90 lbs. . 3. No; it weighs about 45 lbs. . 4. Yes; it weighs about 4.5 lbs.

Answer 1

Volume of gold in the phone = 10 cm^3
= 0.00001 m^3
Density of gold = 19300 kg/m^3
1 kg mass = 2.2 pounds
Mass of 10 cm^3 of gold = 0.00001 m^3 * (19300 kg/m^3)
= 0.193 kg
So
0.193 kg = 0.193 * 2.2 pounds
= 0.43 pounds
I think there is something wrong with the options given in the question.
