The pressure acting on a surface is 10Pa means a force of one 10 Newton exerts on every square meter of area . Also if the a force of F is exerted on an area A , then the pressure P on the area is given by:
P = F/A Pascals,
Thus Pascal is the measure of the unit of pressure and its dimension is N/m^2 or as per dimensional analysis pascal has the indices if mass, length and time expressed like: MLT^-2/L^2 or [ M^1] [L^-1][T^-2].
Nomally pressure per unit area or the unit of pascals are used of mentioning air pressure, liquid pressure , tensile stress , shearing sress etc.
