Pressure is defined as the force per unit area. This measurement is more convenient to use for describing a force exerted. The standard unit for pressure is Pascal. For this problem, force is the gravitational pull from the block. Calculations are as follows:

P = F/A where F = mg

F = 7.5 (9.81) = 73.6 N

P = 73.6 N / 0.6 m^2 = 122.6 Pa
