human body is 255 square inches what is the total weight of the atmosphere on a human body expressesd in pounds

total force= 14.7 lbs/in^2 * 255in^2

To calculate the weight of the atmosphere on a human body, we need to determine the pressure exerted by the atmosphere on a unit of area (in this case, the human body) and then multiply it by the area.

It's important to note that the average pressure exerted by the Earth's atmosphere at sea level is around 14.7 pounds per square inch (psi). However, to get a more accurate estimate, we'll need to convert the 255 square inches of the human body to square feet, as well as consider that not the entire body surface is exposed to the atmosphere.

First, we'll convert square inches to square feet:
1 square foot = 144 square inches

Therefore, the human body is approximately:
255 square inches / 144 = 1.77 square feet

Now let's assume that only a certain percentage of the body's surface area is exposed to the atmosphere. For this explanation, let's use 70%.

So the effective area exposed to the atmosphere is:
1.77 square feet x 0.70 = 1.24 square feet

Next, we'll calculate the weight of the atmosphere on a unit area (1 square foot):
14.7 psi (average atmospheric pressure at sea level) x 1 square foot = 14.7 pounds of force

Finally, we'll multiply the weight per square foot by the effective area exposed to the atmosphere:
14.7 pounds x 1.24 square feet = 18.2 pounds

Therefore, the estimated weight of the atmosphere on a human body (with 255 square inches of surface area) is approximately 18.2 pounds.
