    Answer: (1) 50%
    Explanation:-
    The volume of prism = base area x height
    =A x h
    Where, A = area and h = height of prism
    According to the question,
    The volume of new prism = A x h/2
    The percentage of decrease in volume = (Ah – Ah/2) x 100/Ah
    =  1x 100/2 = 50%
    Hence, the answer is (1)  50%.
