Calculate Force on Wall from Tornado Pressure: N Units

[PeachyKeenZen]

Air within the funnel of a large tornado may have a pressure of only 0.46 atm.
What is the approximate outward force F on a 6.2m x 5.5m wall if a tornado suddenly envelopes the house? Atmospheric pressure is 1.013 x 10^5 Pa. Answer in units of N.

I know that P= F/A, so F=PA. I tryed just multiplying the pressure and area, but that was not correct. I also tried converting atms to Pa and then multiplying; however, that was also incorrect.

Help me, please.

Welcome to PF.

What pressure did you use to find the force?

.46 atm.
I mulitiplied .46 and 1.013 x 10^5 to convert atm to Pa. And I got 46598 Pa and then mulitiplied that by 34.1 m^2 (6.2m x 5.5m) to solve for the force.
