1933—Stop-motion pioneer Willis O’Brien, who brought the giant gorilla to life, once guessed
Kong’s weight at a rather excessive 38 tons.
In the 1933 movie, Kong was about 20 feet tall. In the
2005 version, he was 25 feet tall. Does the data on the
weight of Kong make sense for these heights? Explain.
Weight (mass) is a function of volume and volume of two similar shapes is directly proportional with the cubes of the sides.
Assuming the two gorillas were similar in shape, and assuming that the 2005 data was more accurate, then
weight33/weight05 = height33^3/height05^3
weight33/8000 = 20^3/25^3
weight33 = 4096 pounds
(did they use the 2005 data by using the data from a normal gorilla?
Wikipedia says adult males range in height from 165-175 cm (5 ft 5 in – 5 ft 9 in), and in weight from 140–204.5 kg (310–450 lb)
let's say today's gorilla is 5.5 feet tall and weighs 380 pounds
is 380/4096 = 5.5^3/25^3 ?
LS = .0928
RS = .0106 WAY OFF )
I meant to say
Makes NO sense,
as shown in the calculation.
