Question

A brick 25cm long, 10cm wide and 8 cm thick is lying on the ground. If its weight is 24N, find the
pressure exerted by the brick on the ground.

Answer 1

Hey friend, ☺ here is your answer ____________________________
length of brick = 25cm
breadth of brick = 10cm
height of brick = 8cm

Force = weight = 24N

Now area of brick = length × breadth = 25cm × 10cm = 250cm^2 = 0.025m^2

As we know,
Pressure = Force/area = 24N /0.025m^2 = 960 Pa

Hope this helps you....

Answer 2

Hey mate!

Here's your answer!!

We know that,

$pressure = \frac{force}{area}$

Now, covert m into cm as Newton is N/m²

25 cm = 0.25 m
10 cm = 0.10 m
8 cm = 0.8 m

Area = Length (l) × breadth (b)

So, 0.25 × 0.1 = 0.025 m²

Now,

$\frac{force}{area} = \frac{24}{0.025} = \frac{24000}{25} = 960$

Therefore, the pressure exerted by brick on the ground is 960 N/m² or 960 Pascal.
