Please proof read my solution;
I calculated the pressure acting on the floor when standing on both feet. The areas of my shoes were approximated to be 15cm^2 each, making ti 30cm^2.

Given that I weigh around 58kg, and pressure is calculated as
P=Mg/s (surface area)

P=58kg*9.8m/s^2/0.003m^3=189466.667

The pressure acting on the floor when standing on both feet is given the significant digits of 2
1.9*10^5 Pa
