Question

find the pressure exerted on the floor by a 100N box whose bottom area is 40 cm by 50 cm (use pa for units)​

Answer 1

Actually welcome to the concept of the Pressure and it's Applications

basically here, we know that,

Pressure is defined as force applied per unit area.

thus it's SI unit is N/m^2 or pascals or Pa

So here we get pressure as,

P = F/A

P = 100/ 0.4 * 0.5

P = 100/0.2

P = 1000/2

P = 500 Pa

Answer 2

$\tt{\rightarrow Pressure = \dfrac{Force}{Area}}$

$\tt{\rightarrow Pressure = \dfrac{100}{0.4\times 0.5}}$

$\tt{\rightarrow Pressure = \dfrac{100}{0.2}}$

$\tt{\rightarrow\dfrac{100\times 10}{2}}$

$\tt{\rightarrow\dfrac{1000}{2}}$

Pressure = 500 Pascal
