What is the formula for the area of a scalane triangular prism?

"Volume" = dsqrt(s(s-a)(s-b)(s-c))
where d is the length of the prism,
a, b, c are the lengths of the 3 sides of the scalene triangle,
and s is the semi-perimeter of the scalene triangle (i.e. (a+b+c)/2)

Explanation:

I assume you meant "volume" and not "area" since a prism is a 3-D construct.

sqrt(s(s-a)(s-b)(s-c)) is Heron's formula for the area of a triangle with sides a,b,c
