Given the following cross sections:

Station $9+45$:

$=1500f{f}^3$

Station $10+00$:

Station $10+15$:

Find:

a$)$ The volume $($in Cubic yards$)$ between stations $9+45$ and $10+15$ by the Average$-$End$-$Area Method.

b$)$ The volume $($in Cubic yards$)$ between station $9+45$ and $10+15$ by the Prismodial Method.

c$)$ The Prismoidal correction $-$ Cv $($in Cubic yards$).$
