Question 1154328
.
<pre>

(a)  Since the hypotenuse is 8.5 cm and sinse the triangle is right and isoscels,

     the legs are congruent and have the length of  {{{8.5/sqrt(2)}}} cm each.


     Therefore, the area of the right triangle at the base is  {{{(1/2)*(8.5/sqrt(2))*(8.5/sqrt(2))}}} = {{{(1/2)*((8.5*8.5)/2)}}} = {{{8.5^2/4}}}.


     Hence, the volume of the prism is  {{{(8.5^2/4)*12}}} = {{{3*8.5^2}}} = 216.75 cubic centimeters.    <U>ANSWER</U>



(b)  you just know each and every dimension of the prism.


     Finding its surface area is just simple arithmetic.
