The volume of a pyramid can be evaluated by using the equation V Ah 3 1 = where h is the height of the pyramid and A is the area of the base of the pyramid. The problem is to design such a triangular pyramid where the volume is V = 72 cm3 and the height is h = 12 cm. The base of the pyramid is a rectangular isosceles triangle. a) Determine the area of the base of the pyramid. Pay attention to the unit of your answer. b) Draw a picture of the base triangle of the pyramid in a proper scale.

    just one question, how can you have a rectangular isosceles triangle? It's either a recatangular base or a triangular one lol

    Okay, if it's a rectangular base then the Area of the base = LW , so :\[V =Ah/3 \]\[A = (72)(3)/12 = 18cm^2\] Or, if the base was triangular: \[A = bh/2\] then: \[V = Ah/6\] \[A = (6)(72)/12 = 36 cm^2\] that's for part (a)

    same same , so I guess it's a rectangular base after all ^_^

    maybe, rectangular is a trick in the question and the base is triangular after all. I agree. ^^"
