If $L={100}^{\text{'}}$ and $W={1\mathrm{.}5}^{\text{'}},$ what is quantity of formwork $($in SFCA$)$ needed for this a footing? $($hint: you need formwork on all

four sides of the footing$)$

$204$ SFCA

$203$ SFCA

$164$ SFCA

$163$ SFCA

If $L={80}^{\text{'}}$ and $W={1\mathrm{.}5}^{\text{'}},$ estimate the quantity of steel reinforcement $($in tons$)$ for the footing.
