Given parameters:
Pressure = 250000Pa
Weight = 40000N
Unknown:
Area of each foot = ?
Solution:
Pressure is the force exerted per unit area of a body
Pressure =
To find the area;
Area =
Area = = 0.16m²
The force exerted by all the four feet is 0.16m²
the area of each feet = = 0.04m²

Answer:
<h2> 242.5kPa</h2>Explanation:
According to one of the gas laws,
Given P1 = 240.0kPa, T1, 15.0°C, T2 = 18.0°C, P2 = ?
Substituting this values into the equation, we have;
Cross multiplying we have;
288P2 = 240*291
The new pressure is 242.5kPa
