Assume that at sea-level the air pressure is 1.0 atm and the air density is 1.3 kg/m3.
(a) What would be the height of the atmosphere if the air density were constant? 7.919 km
(b) What would be the height of the atmosphere if the air density decreased linearly to zero with height?
I need help on part b

b) figure the height if the air density was the average of 1.3 and 0, or 1.3/2

h*area*density*g=101300N*area
h= 101300/(g*density) in meters
