With what force does the atmosphere press on the 110 cm by 50 cm lid of the student’s table

With what force does the atmosphere press on the 110 cm by 50 cm lid of the student’s table, is atmospheric pressure considered normal?

a = 110 cm = 1.1 m.

b = 50 cm = 0.5 m.

P = 101325 Pa.

F -?

The pressure of the force p is the ratio of the force F to the area S on which this force acts.

Pressure P is determined by the formula: P = F / S.

Let us express the force of pressure: F = P * S.

Since the table top has the shape of a rectangle, its area S is determined by the formula: S = a * b, where a and b are the sides of the rectangle.

F = P * a * b.

F = 101325 Pa * 1.1 m * 0.5 m = 55728.75 N.

Answer: the atmosphere presses on the lid of the desk with a force of F = 55728.75 N.
