Question

The mass of a brick is 250 g. Its dimensions are 10 cm X 5 cm X 2 cm. Find the pressure the brick exerts on the ground if it rests on: i) the 10 cm X 5 cm side.

Answer 1

Answer:

5000 pa

Step-by-step explanation:

Mass of the brick = 250 g

= 2.5 kg

= 25 Newton

Volume of the brick = 10cmX5cm

= 50 cm square

= 0.005 m square

Pressure on ground = mass ÷ volume

= 25÷0.005

= 5000 pa

So, the total pressure exerted over the ground is 5000 pa.

Answer 2

Step-by-step explanation:

Mass of the brick = 250g

= 2.5kg

=25 N

Volume of the brick=10cm× 5cm

=50cm Square

=0.005m

Pressure on ground=mass÷volume

= 25÷0.005

= 5000pa
