Exploding People

Still on the subject of exploding people watch the following clip and then try to solve the problems.


Assuming the man weighs 12 stone and that the average density of a human being is 1.4 g/cm cubed what is his volume?

If the man was broken into pieces approximately 2cm by 2cm by 2cm (approx. 1 inch cubes) how many pieces would the FBI agents have to pick up?

Estimate the weight of the ear that Walter Bishop holds up in the video.

  1. 12 stone = 12 x 14 lb = 168 lb
    168 / 2.2 = 76.36 kg

    At 1.4 g per cubic centimetre = (76.36 x 1000) / 1.4 = 54545 cubic cm.

    54545 / (2 x 2 x 2) = 6818 pieces approximately

    Estimate ear to be 6 cm x 3 cm x 0.5 cm = 9 cubic cm. = 9 x 1.4 = 13 g (approximately)
