Question

1.
A cubical box has sides measuring 20 cm each. It exerts a force of 80 N on the table where it is kept. Calculate the pressure exerted by the box.
(Hint: 100 cm = 1 m)​

Answer 1

Explanation:

as we know , pressure =force / area

force =80N,area=.2#.2= .04sq m

pressure=80/.04

=80#100/4

=2000N/sqm or2kn/sqm
