Question 72443
a) The weight of the Gorila when its height was half the present height its weight was half the present i.e. {{{400/2=200}}} lbs.


b) Weight of the Gorilla is proportional to its height.


c) Here, {{{PRESSURE}}} = {{{WEIGHT/AREA}}}

WEIGHT = 200 lbs
AREA = 1 feet square = area of a square with sides 1 ft = 1x1 sq. ft. = (12)x(12) sq. inch = 144 sq. in.

So, {{{PRESSURE}}} = {{{400/144}}} = {{{400/144}}} = 2.78 psi
