Answer:
105 N
Step-by-step explanation:
You want the force exerted on an area 2 m by 1.25 m by a pressure of 42 N/m².
Area
The area is ...
A = LW
A = (2 m)(1.25 m) = 2.50 m²
Force
The force is the product of the pressure and the area:
F = PA
F = (42 N/m²)(2.5 m²) = 105 N
The box exerts a force of 105 N on the table.
