A cubic box of volume 4.1×10^2 m^3 is filled with air at atmospheric pressure at 20 degrees C. The box is closed and heated to 181 degrees C. What is the net force on each side of the box?

The edge size of the box is
a = (0.041)^(1/3) = 0.345 m
and the area of a side is 0.1189 m^2
Pressure increases by a factor (273+181)/(273+20) = 1.5495
The new pressure will be 1.5495 atm
Multiply the final pressure (in Pascals) by the box side area, for the force in Newtons. I will leave that step up to you.
