ok my problem is that the question asks
The palm of Sheila's hand has an area of 0.0017m2.If the atmospheric pressure on the palm is 100,000 Pa, what force is being exerted on Sheila's palm by the atmosphere?

I know the formula is not P=F/A
I know you have to change the formula around but I don't know which way...
is it F=P/A?Or something esle?

Thanks for people that are answering!

Um...can't remember this formula off the top of my head, but if you start with P=F/A, you can't get it to F=P/A.
 
Pressure is F/A. Manipulating it gets you F=PA
 
P = F / A leads to

F = P*A
 
thanks...
