Total tons of rebar required is For Questions $17-21$

Estimate the volume of concrete $($CY$),$ tons of rebar, and SFCA of formwork for the $6"$ slab below. The slab has $\backslash$#$4$ rebar at $14"$ OC in the east to west orientation and $\backslash$#$5$ rebar at $12"$ OC in the north to south orientation. The weight of $\backslash$#$4$ rebar is $\backslash (0\mathrm{.}668\backslash$mathrm$\{$lbs$\}/\backslash$mathrm$\{$If$\}\backslash )$ and the weight of $\backslash$#$5$ rebar is $\backslash (1\mathrm{.}043\backslash$mathrm$\{$lbs$\}/\backslash$mathrm$\{$If$\}\backslash ).$ Assume a $\backslash (24\backslash$varnothing $\backslash )$ lap for the $\backslash$#$4$ rebar and $22$ lap for the $\backslash$#$5$ rebar $($assume $20\text{'}$ bar lengths$).$
