Part $3.$ The elevation $(H)$ calculated from a total station is calculated with the following formula:

$H=H_0+h_i+H-h_r$

$H_0=2524\mathrm{.}872+1-0\mathrm{.}003ft$

$h_i=4\mathrm{.}23+1-0\mathrm{.}01ft$

$H=45\mathrm{.}165+1-0\mathrm{.}003ft$

$h_r=3\mathrm{.}94+1-0\mathrm{.}01ft$

What is the final elevation with the following values $($round to the correct significant figures$)?$

Part $4.$ What is the error for the elevation value above?
