Question 1061652
I'll give it a shot:
The formula for surface area of a
triangular prism is:
{{{ A = a*b + 3b*h }}}
{{{ h = 6 }}} cm
{{{ a = 2.9 }}} cm
{{{ b = 10 }}} cm
-------------------
{{{ A = 2.9*10 + 3*10*6 }}}
{{{ A = 29 + 180 }}}
{{{ A = 209 }}} cm2
--------------------
[ cost ] = [ cm2 ] x [ cost/cm2 ]
{{{ C = 209*.0005 }}}
{{{ C = .1045 }}} dollars
