Right triangle PQR is the base of the prism in the figure above. If PQ=PR=âˆš5 and the height of the prism is 10, what is the volume of the prism?  Pick one:
A) 5	B) 10	C) 15	D) 20	E) 25
Volume of prism = Area of base * height = 1/2* (square root of 5) * (square root of 5)*10 = 25   Answer: 25
<result>E</result>
