If a 370 kN load is applied on a rectangular foundation with dimensions of 4 m x 6 m, located at the top of the soil surface, using the 2:1 approximation method:

a) What would be the increase in stress at a 7.5 m depth of soil? Please draw out the diagram showing how the length of the foundation changes in the 2:1 approximation with the depth showing the new area at the specific depth stated.

b) What would be the stress at the surface level of the foundation?
