Question

A block of wood of mass 6kg and dimensions 50 cm *30cm*20cm is placed on a table top.find the pressure exerted if the block lies on the table top with sides of dimensions.

Answer 1

P=F/A

F=mg   =  6x9.8=58.8N
A=(50x30x20)/10^6=0.03m^2
P=58.8/0.03=1960N/m^2 

Answer 2

P=f/a
f=mg=6×9.8=58.8N
A=(50×30×20)/10^6=0.03m^²
p=58.8/0.03=1960Nm^²
