1.165 X 10^19 pounds

The average atmospheric pressure is 14.7 lb/sq. inch.

Earth's radius = 3964 miles = $2.5116 X 10^{8},$ $2.5116 X 10^8",$ nearly.

The surface area of the Earth

= $4 π {(r a d i u s)}^{2}$ $4 pi (radius)^2$

$= 7.927 X 10^{17}$ $=7.927 X 10^17$ sq. inch.

$= (7.927 X 10^{17}$ $=(7.927 X 10^17$ sq. inch) X (14.7 lb/sq. sq. inch)

$= 1.165 X 10^{19}$ $=1.165 X 10^19$ pounds
