Pressure exerted on the brick at bottom is due to the force exerted by its weight divided by its area.
Pressure= Force / Area
here according to the question, Force (F)=16N
Area= length x breadth
Area=32cmx10xcm
=(32/100)m X( 10/100 )m
=0.32m x0.1m
=0.032m²
Pressure= Force / Area
=16/0.032
=500N/m²
Thus, the pressure exerted by the brick on the ground is 500N/m² or 500 Pa
