A $16-$foot$-$high by $51-$foot$-$long wall is faced with $\frac{71}{2}-$ inch$-$long by $\frac{21}{2}-$inch$-$high

bricks. The mortar joints between the bricks are $\frac{1}{2}-$inch thick. Using the area method,

determine the number of bricks needed to face the wall.

How many cubic yards of concrete are required to construct a $80-$foot$-$long by $28-$inch$-$

wide by $10-$inch$-$thick continuous footing? Include $10\%$ waste. Concrete must be ordered

in quarter$-$yard increments. Determine the length of forms needed. The footing has three

#$6$ continuous bars. The rebar is lapped $18$ inches. Determine the number of $20-$foot$-$long

bars that needs to be ordered for the footing.

How many cubic yards of concrete are required to construct $8$ each $40-$inch by $15-$inch by

$20-$foot$-$high concrete columns? Include $6\%$ waste. Concrete must be ordered in quarter$-$

yard increments. Determine the square footage of forms needed.
