You have been chosen to be the one of few to go to Mars. On Mars
you have a standard 55 gal water drum (height = 35 in, diameter =
23 in) filled with water. You are unlucky that the pump is broken
to get the water out. But you are an a NASA astronaut, you find a
spike (length = 6.5 in to the point, width = 0.5 in and 0.5 in) and
a hammer. You need the water...
