$V=lwh$
$V=(6\times\frac{1}{3})(4\times\frac{1}{3})(8\times\frac{1}{3})$
$V=(\frac{6}{3})(\frac{4}{3})(\frac{8}{3})$
$V=\frac{64}{9}$
$V=7\frac{1}{9}$

−5x2−9x+8−5x2−9x+8−−6x2+5−6x2+5

=−5x2+−9x+8+−5x2+−9x+8+6x2+5+−6x2+5

Combine Like Terms:

=−5x2+−9x+8+−5x2+−9x+8+6x2+5+−6x2+5

=(−5x2+−5x2+6x2+−6x2)+(−9x+−9x)+(8+8+5+5)
