Question

Find the pressure exerted on the floor by a 100N box whose bottom area is 40cm x
50cm.

Answer 1

500Pa

Step-by-step explanation:

Pressure = Force / Area where area is in
`m^(2)`.

Firstly, lets convert both area dimensions into metrers.

40cm = 40/100 m = 0.4m

50cm = 50/100 m = 0.5m

Area of Bottom area of box = 0.4m x 0.5m =
`0.2m^(2)`

Pressure =
`(100N)/(0.2m^(2) )`

= 500Pa

Answer 2

Pressure exerted = 500 Pa

Step-by-step explanation:

The formula for pressure is as follows:

`Pressure = (Force \space\ applied)/(Area)`

In this case,

Force applied = 100N

Area = 40cm × 50cm = 2000cm² = 2000 × 10⁻⁴ = 0.2m²

Substituting these values into the formula:

Pressure =
`(100)/(0.2)`

⇒ Pressure = 500 Pa
