Answer:
P = 1960 Pa
Explanation:
The pressure is computed as the force acting upon a surface divided by the area of the surface
[tex]P=\frac{F}{A}[/tex]
The box has 40 kg, it presses on its own surface when placed over a table or any flat area. The acting force is its weight.
[tex]F = W = m.g = 40 kg \ 9.8m/sec^2 = 392 N[/tex]
The pressure is:
[tex]P=\frac{392N}{0.2m^2}=1960 \ Pa[/tex]
