Question

The bottom of a box has a surface area of 25.0 cm2. The mass of the box is 34.0 kilograms. Acceleration due to gravity at sea level is 9.80 m/s2. What pressure is exerted by the box where it rests?

Answer 1

weight =mg = 333.2 N
pressure = force/area = 333.2/25=13.328 N/cm^2

Answer 2

Pressure, P = 133280 pascal

Step-by-step explanation:

Given that,

Surface area of the box,
`a=25\ cm^2=0.0025\ m^2`

Mass of the box, m = 34 kg

To find,

The pressure exerted by the box

Solution,

The force acting per unit of area is called the pressure exerted. Its expression is given by :

`P=(F)/(A)`

`P=(mg)/(A)`

`P=(34* 9.8)/(0.0025)`

P = 133280 pascal

So, the pressure exerted by the box is 133280 pascal.
