A man is placed inside a metal cube of edge 8 feet.
There are no windows in the cube, no inlet of air of any kind, and the door he came in through has been hermetically sealed from the outside.
The man is completely naked. He is 6 feet tall and weighs 75 kgs.
The only other object in the box with him is a handgun. The gun is loaded and contains 6 bullets.
The walls of the cube are made of reinforced steel. A bullet striking the side of the cube will ricochet. The only thing soft enough to stop a bullet in this entire arrangement is the man's body.
With minimal activity levels, the air in the cube will last the man for upto 4 hours. Beyond that point the man will suffocate due to lack of oxygen.
Under no circumstances can the cube be opened for the next 24 hours. The man inside the cube knows this.
The man has the following options:
a) Take the gun and shoot himself in the head
b) Fire the gun randomly at the sides of the cube and wait to see where the ricochets strike him
c) Put the gun aside and wait patiently to die of suffocation
d) Disable the gun by smashing it against the metal walls and then wait patiently to die of suffocation.
e) Jump around inside the cube thus using up oxygen faster and hastening his death by suffocation. (Option e can be combined with either option c or option d)
