ALL prisms have the formula
Volume = \(A_b*h\)
where
\(A_b = \) area of base (of prism)
h = height of prism
Area of a triangle = \(\dfrac {base \times height}{2}\)
where
base = length of base of triangle
height = height of triangle

C.
216 cm3
D.
532 cm3
OpenStudy (mathmate):
Yes, the area of the base of the prism is 12.
Do not forget, question wants the \(volume\) of the prism.
Use the other formula to finish the problem.
OpenStudy (mathmate):
Sorry, I am not interested in the answer choices. I am interested what you calculate and how you got it.
