The dimensions of a brick that weighs 25 N are 0.19 m × 0.07 m × 0.095 m. What pressure does the brick exert on the ground if it is resting on its largest face?

P - pressure [Pa]
Fn - pressure force [N]
S - surface area [m²]
S = 0.19m*0.095=0.01805 [m²] (the two largest values of bricks)
$p=\frac{F_n}{S}=\frac{25N}{0.01805m^2}=1385[Pa]$

Rate answer

Answer:

The pressure of the brick exert on the ground if it is resting on its largest face is 1385.04 Pa.

Explanation:

Given that,

Weight of brick = 25 N

The dimensions of a brick are 0.19 m × 0.07 m × 0.095 m.

The pressure of the brick exert on the ground if it is resting on its largest face.

So, The area of largest face of brick is

$A = 0.19\times 0.095$

$A= 0.01805\ m^2$

The pressure of the brick on the ground is

The pressure is the force upon area.

The formula of pressure is

$P =\dfrac{F}{A}$

$P=\dfrac{25}{0.01805}$

$P = 1385.04\ Pa$

Hence, The pressure of the brick exert on the ground if it is resting on its largest face is 1385.04 Pa.
