Question

A brick measures 225mm×112mm×75m has a mass of 3.10 kg calculate the pressure the brick creates standing on its surface of smallest area and greatest area
​

Answer 1

Explanation:

In this case greatest area=225mm×112mm

=225/1000m×112/1000m

Here force =Weight

=mg

=3.1×10

=31 N

So P=N/A

=31/(225/1000×112/1000)

=31×1000/225×1000/112

=1230.15 Pa(approx.)
