Question

( pls answer )A brick weighs 24 N occupies an area of 300 sq cm. Find the pressure exerted by the brick on the ground?
a.0.08 Pa
b. 0.8 Pa
c.800 Pa
d.80 Pa​

Answer 1

Provided that:

• Weight = Force = 24 N
• Area = 300 sq. cm

To calculate:

• Pressure

Solution:

• Pressure = 800 Pa

Using concepts:

• Formula to convert cm² - m²
• Pressure formula

Using formulas:

• 1 cm² = 1/10000 m²
• Pressure = Force/Area

Required solution:

✡️ Firstly let us convert centimetres square into metres square by using suitable formula!

→ 1 cm² = 1/10000 m²

→ 300 cm² = 300/10000 m²

→ 300 cm² = 3/100 m²

→ 300 cm² = 0.03 m²

• Henceforth, converted!

✡️ Now let us calculate the pressure by using suitable formula!

→ Pressure = Force/Area

→ Pressure = 24/0.03

→ Pressure = 800 Pascal

• Henceforth, solved! $\:$

Answer 2

From the given question the correct answer is :

c.800 Pa

Solution:

Given:

Weight = Force = 24 N

Area = 300 sq. cm

To find:

Pressure

Solution:

Pressure = 800 Pa

Using concepts:

Formula to convert cm² - m²

Pressure formula

Using formulas:

1 cm² = 1/10000 m²

Pressure = Force/Area

Required solution:

Firstly let us convert centimetres square into metres square by using suitable formula!

→ 1 cm² = 1/10000 m²

→ 300 cm² = 300/10000 m²

→ 300 cm² = 3/100 m²

→ 300 cm² = 0.03 m²

Henceforth, converted!
