Show me the steps to solve DATA on the foundation ground conditions of the warehouse in situ:

Drained conditions:

$C^{\text{'}}=3$kPa,${}^{\text{'}}=27c_u=96$kPa

Ground Water table levels at height $+56,10m$

DATA on in situ wall foundation ground conditions:

$c_u=96$kPa

${}^{\text{'}}=18k\frac{N}{m^3}$

Ground Water table levels at height $+56,10m$

Lot data for the design of the buried reinforced concrete storeroom:

Angle of internal earth friction ${}^{\text{'}}=27,5$ o

${}^{\text{'}}=19k\frac{N}{m^3}$

Ground Water table levels at height $+56,10m$
