ahemm ok... so...notice the base of the "triangular pyramid" let us lift it up some, so we can take a peek |dw:1454371701588:dw|

OpenStudy (jdoe0001):

so not to confuse, the pyramid itself has that base and the base is just a triangle, that itself, when put UP, has a base and a height

OpenStudy (shaleiah):

3*4

OpenStudy (jdoe0001):

yeap so...now that we know the base and height of that triangle (which is the base of the pyramid) what would be the area of that triangle?

OpenStudy (shaleiah):

If the formula is 3*4/2 it would be 6.

@jdoe0001

OpenStudy (jdoe0001):

yes so.. now we know the area of that triangle (which is the base of the pyramid) well.. now just notice the height of the pyramid and keep in mind that |dw:1454372162818:dw| so.. what do you think is the area of that pyramid then?

OpenStudy (jdoe0001):

hmm hmm hold ... rats.. you need the volume

OpenStudy (jdoe0001):

lemme hmmm is correct, just lemme reword that some :) |dw:1454372305953:dw|

OpenStudy (shaleiah):

4

OpenStudy (jdoe0001):

4?

OpenStudy (jdoe0001):

check again we know the area of the pyramid's base is 6 we know the height of the pyramid is 6 we know the \(\bf \textit{volume of a pyramid}=\cfrac{1}{3}\cdot Base\cdot height\) so... what does that give us for volume?

OpenStudy (jdoe0001):

\(\bf \textit{volume of a pyramid}=\cfrac{1}{3}\cdot 6\cdot 6\implies ?\)
