Assume that the width of your body (across your shoulders) is 50.8 cm inches and the depth of your body (chest to back) is 25.0 cm. If the atmospheric pressure is 14.9lb/in^2, what mass of air (lb) does your body support when you are in an upright position?

Answer 1

50 cm x 2.54 cm/in = ? in
25 cm x 2.54 cm/in = * in

area = ?in x *in = c in^2

pressure = 14.9 (is that right?)
lb/in^2 x c in^2 = ?

Answer 2

Yeh its 14.9 lb/in^2
