Question

A brick of length 30 cm, breadth 10 cm and width 10 cm apply a weight of 24 n on it. Calculate the pressure exerted by the brick

Answer 1

$\mathfrak {AnSwEr}$

We know that :

Pressure = Force / Area

Area = 30 × 10 × 10 = 3000 cm^2

Force = 24 N

Pressure = 24 / 3000

Pressure = 0.008 Pa

Answer 2

Answer:

0.008 Pa

Explanation:

Given,

Force = 24 N

Area = ?

Area of brick = l × b × h

Area of brick = 30 × 10 × 10

Area of brick = 300 × 10

Area of brick = 3000 cm²

Now,

Pressure = Force / Area

In terms of mathematical physics, pressure is defined as when the force is divided by the area.

P = F / A

=> P = F / A

Putting the given values.

=> P = 24 / 3000

=> P = 8 / 1000

=> P = 0.008

.°. Pressure = 0.008 Pa
