The triangle has sides "a", "b" and "c", where side a = side b and the hypotenuse (side "c") equals side "a" or "b" times the square root of 2.
Prism volume = triangle area * height 342.1 = triangle area * 13.2 triangle area = 342.1 / 13.2 <span><span><span>triangle area = 25.9166666667
</span>
</span>
</span>
area of a triangle is (1/2) base * height In a 45 45 90 triangle, the base = height and since we don't know either the base or the height we'll call both "x". So triangle area = (1/2) * x^2 <span>25.9166666667 = (1/2) * x^2 x^2 = </span><span>51.8333333334
x ( the base and the height) = </span><span><span><span>7.1995370222
</span>
</span>
</span>
<span>
</span>
the hypotenuse of a 45 45 90 triangle = leg * square root (2) = hypotenuse = <span>7.1995370222 * sq root (2) </span><span><span><span>hypotenuse = 10.1816828995
</span>
</span>
</span>
So, one of the legs = <span><span>7.1995370222
