With what force does the atmosphere press on the surface of a notebook measuring 16 * 20 at atm. pressure of 0.1 MPa.

The force of pressure on the notebook is determined by the formula
F = p * S,
Where
p = 0.1MPa = 100000Pa – atmospheric pressure,
S is the surface area of the notebook (dimensions are given in cm-ah):
S = 16cm * 20cm = 0.16m * 0.2m = 0.032m ^ 2;
F = 100000Pa * 0.032m ^ 2 = 100000N / m ^ 2 * 30.032m ^ 2 = 200H.
