Answer: 76 N

Step-by-step explanation:

The formula for calculating pressure is expressed as

Pressure = force/area

To calculate the area, we would appply the formula for calculating the

area of a rectangle which is expressed as

Area = length x width

From the information given,

length = 0.334

width = 0.568

Pressure = 400 Pa

Recall, 1 pa = 1n/m^2

400 Pa = 400 n/m^2

Area = 0.334 x 0.568 = 0.189712 m^2

The formula for calculating force is

Force = 0.189712 x 400

Force = 76 N
