Question

2. A brick is 30 cm long, 10 cm wide and 10 cm thick. It weighs 24 N and is lying on the ground. Find the pressure exerted by the brick on the ground. The answer is 800 pa. But how, please explain.....

Answer 1

Answer:

Explanation:

Pressure = Force/Area

Assuming that the brick lies on its largest face, it will have area = 30cm * 10cm = 300 cm^2 = 0.03 m^2

Hence pressure = 24N/0.03m^2 = 800Pa

Answer 2

Pressure = Force/Area

Assuming that the brick lies on its largest face, it will have area = 30cm * 10cm = 300 cm^2 = 0.03 m^2

Hence pressure = 24N/0.03m^2 = 800Pa
