$\Large\underbrace \frak\red{Question}$

Brick is 30cm long, 10 cm wide and 10 cm thick. It weights 24N and is lying on the ground. Find the pressure exerted by the brick on the ground.

$\Large\underbrace \frak\red{Answer}$

${\underline{ \underline{ \pink{800 \: {N/m}^{2} \: or \: 800 \: Pa}}}}$

$\Large\underbrace \frak\red{solution}$

Here, force (F) = 24N

Area (A) of contact ( l × 6 ) between the brick on the ground

= 30cm × 10 cm

= 0.3m × 0.1m = {0.03}^{2}m

We know pressure (P) = \frac{Force(F)}{Area(A)}

So, P = \frac{24N}{0.03}^{2}m

= 800 {N/m}^{2} or 800 Pa
