Here it is given that,
Mass of Boy = 45 kg
Side of square wooden box = 50 cm = 0.5 m
In order to find Pressure, At first we have to find Area and Thurst as well.
Area of Square wooden box= side^2= (0.5)^2 m^2 = 0.25 m^2
Thurst = mg ( where m=mass and g=gravitational force)
F = (45 x 10) Kg m/s^2
=> F = 450 kg m/s^2
Now,
Pressure= Thurst/Area
=> P= F/A
=> P= (450/0.25) Pa
=> P= 1800 Pa
