Quizplus · Accepted Answer

The average person has about 21 square feet of skin. This is calculated by using the formula for the surface area of a cylinder (the body), which is 2πr² + 2πrh. For a six-foot-tall person, this means a radius of about 4 inches and a height of 72 inches, giving a surface area of approximately 21.39 square feet.
