If a board with an area of 3m2 has a 12 N force exerted on it, what is the pressure on the board?
Cerrena [4.2K]
4 N/cm^2 is the answer. the way you get this is the formula for pressure is P=F/A. So you would plug in the numbers which would make the equation P=12/3 which you know equals 4. The units for pressure is N/cm^2 or N/m^2

I hope this helps
