So hmm notice the picture below

is a "square" pyramid, thus, the base is a square, all sides are the same

now, we know the volume is 75 and one side is 5

thus \bf \textit{volume of a pyramid}\\\\
V=\cfrac{1}{3}\cdot Base\cdot height\qquad 
\begin{cases}
Base=length\cdot width\\
\qquad\qquad  5\cdot 5=25\\
V=75
\end{cases}\\\\\\ 75=\cfrac{1}{3}\cdot 25\cdot h

solve for "h" or height

Starting salary in 2013 at $34,862

Generally  comparable starting salary C is given as

   C=\frac{starting salary}{CPI for 2013(index} *CPI for 2003(index)

   C=\frac{34,862}{232.957} *184

Therefore C the comparable starting salary is givrn to be
