Pressure is defined as force per unit area, which in this case works out to be 2.917 kPa

Explanation:

One pascal of pressure is exerted by a force of one newton applied over an area of one square metre.

So, for a 1750 N force applied to 0.6 #m^3#, we find

#P=F/A# = #(1750N)/(0.6 m^3)# = 2917 Pa or 2.917 kPa
