What is the height of the mountain, if at the foot of the atmospheric pressure is 725 mm Hg? , and at the top 689 mm Hg?

We know that with an increase in altitude, atmospheric pressure drops, for every 1000 m of rise, the pressure decreases by 100 mm, or 10 mm for every 100 m of rise, so if the atmospheric pressure at the foot is 725 mm Hg. Art., and at the top 689 mm Hg. Art., then the pressure difference will be

725 – 689 = 36 mm

from here

100 m – 10 mm

x m – 36 mm
x = 36 x 100/10

x = 360

The relative height of the mountain will be 360 meters.
