Question

A brick is 64 cm long and 20 cm wide and 20 cm thick it weighs 32 and and is lying on the ground find the pressure exerted by brick on the ground

Answer 1

Explanation:

The formula of pressure = force/area

Then,32/1280 = 0.025

Answer 2

Answer:

hope it helps u

Explanation:

Converting the units from cm to m, we have the dimensions as-

0.32 m

0.1 m

0.1 m

Area in contact with ground = 0.32 x 0.1 = 0.032 m²

We know that, Pressure = Force/Area

                                         16/0.032     =   500 N/m²  = 500Pa

                                                           or

Pressure exerted on the brick at bottom is due to the force exerted by its weight divided by its area.

Pressure= Force / Area

Where F=16N

area= lengthx breadth

area=32cmx10xcm=(32/100)mX( 10/100 )m

=0.32m x0.1m=0.032m²

Pressure=16/0.032=500N/m²

Pressure exerted by the brick  is 500N/m² or 500 Pa
