The given cross$-$section notes of earthworks between Sta $1+040$ and Sta $1+100$ are

shown below for a portion of road to be constructed

Notes:

Base length for cut section $=9\mathrm{.}0m$ with sideslopes at $1$:$1$

Base length for fill section $=8\mathrm{.}0m$ with sideslopes at $1\mathrm{.}5$:$1$

Compute the area of Sta $1+040.$

Compute the area of Sta $1+100.$

Determine the difference in volume of cut and fill using end area method.
