Question $2$:

A longitudinal leveling $($One point per section$)$ was performed along road centerline as follows:

Given that the elevation of the road at the start station is $56\mathrm{.}50m$ and it slopes $1\mathrm{.}0\%$ downwards.

The road width is $10m$ with side is $3$:$2(H$:$V).$ It is required to:

$1-$ Draw a profile with scale $1$:$1000H{z}_Z$ and $1$:$100V_L,$ showing existing ground and road level.

$2-$ Draw a cross$-$section at stations $0$ and $125m$ with scale $1$:$250$

$3-$ Calculate the cross$-$sectional areas at ALL stations,

$4-$ Calculate the volume of earthworks, using Simpson's rule, wherever applicable.

$5-$ Calculate the volume of earthworks, using trapezoidal rule.
