(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   cm each.


     Therefore, the area of the right triangle at the base is   =  = .


     Hence, the volume of the prism is   =  = 216.75 cubic centimeters.    ANSWER



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


     Finding its surface area is just simple arithmetic.
