Question 45434
height = h
length = h + 9
width = h - 4
{{{lwh = V}}}
{{{h(h + 9)(h - 4) = 180}}}
{{{(h^2 + 9h)(h - 4) = 180}}}
{{{h^3 + 5h^2 - 36h - 180 = 0}}}
{{{ graph( 600, 600, -10, 10, -10, 10, x^3 + 5x^2 - 36x - 180 ) }}}
{{{(h + 6)(h + 5)(h - 6) = 0}}}
height = 6
length = h + 9 = 15
width = h - 4 = 2
