Prepare a set of three$-$wire leveling notes for the

data given and make the page check. The elevation

of BM X is $876\mathrm{.}98$ ft $.$ Rod readings $($in feet$)$ are $(U$

denotes upper cross$-$wire readings, $M$ middle wire,

and L lower wire$)$: $+$S on $BMx$:$U=5\mathrm{.}489,$

$M=4\mathrm{.}739,L=3\mathrm{.}990$;$-S$ on TP $1$:$U=6\mathrm{.}843,$

$M=5\mathrm{.}918,L=4\mathrm{.}996$;$+S$ on TP $1$:$U=7\mathrm{.}984,$

$M=6\mathrm{.}969,L=5\mathrm{.}952$; $-S$ on $BMY$:$U=4\mathrm{.}872,$

$M=4\mathrm{.}022,L=3\mathrm{.}173.$

Part A

Assuming a stadia constant of $99\mathrm{.}886,$ what is the distance leveled?

Express your answer in feet to three decimal places.
