How much force (in n) is exerted on one side of an 16.2 cm by 22.9 cm sheet of paper by the atmosphere

The 16.2cm by 22.9cm paper has an area = 370.98 square cm = 0.037098 square meters. And the atmospheric pressure at sea level is 101,325 Newtons per square meter. So if multiply the quantities: 101,325 N/m^2 and 0.037098 m^2 we get an answer of 3758.95 N. * If we respect the fact that 22.9cm and 16.2 cm only have three significant digits then our answer would be 3760N.
