Question

11. A 30-kg box is 0.2 m long and 0.15 m wide. What pressure does it exert on the floor?

Answer 1

P = 9800 Pa

Step-by-step explanation:

Given that,

The mass of a box, m = 30 kg

Length of the box, l = 0.2 m

The width of a box, b = 0.15 m

We need to find the pressure it exerted on the floor. Pressure is equal to force acting per unit area. So,

`P=(F)/(A)\\\\=(mg)/(lb)\\\\=(30* 9.8)/(0.2* 0.15)\\\\P=9800\ Pa`

So, 9800 Pa of pressure is exerted on the floor.
