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)

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