If the surface area of a human body is 16,700 square centimeters, what is the total weight of the atmosphere on a human body expressed in pounds?
Convert 16,700 cm^2 to in^2. I would use Google for that.
Then in^2 x 14.7 lb/in^2 = ? lbs.
To calculate the weight of the atmosphere on a human body, we need to know the average atmospheric pressure and the surface area of the body. However, the given information only provides the surface area of the body, which is 16,700 square centimeters.
To proceed, we can make an approximation by assuming that the average atmospheric pressure is equivalent to the standard sea-level pressure, which is approximately 14.7 pounds per square inch (psi).
Now, to convert the surface area from square centimeters to square inches, we need to multiply it by the conversion factor 0.1550 (since 1 square inch = 6.4516 square centimeters). Therefore, the surface area in square inches is:
16,700 square centimeters * 0.1550 = 2,588.5 square inches.
Next, we can calculate the weight of the atmosphere on the body by multiplying the surface area by the atmospheric pressure. This will give us the force exerted by the atmosphere, measured in pounds. Thus, the weight is:
2,588.5 square inches * 14.7 psi = 38,029.95 pounds.
Therefore, the approximate weight of the atmosphere on a human body, based on the given information, is approximately 38,030 pounds.
