OpenStudy (anonymous):

i dont know how to find the height of this shape

OpenStudy (anonymous):

To find the height use a right triangle and pythagorean theorem

OpenStudy (anonymous):

so 15.3?

OpenStudy (anonymous):

The bottom edge of the pyramid is 8 so the bottom of the fight triangle is half that

OpenStudy (anonymous):

And the hypotenuse is 13

OpenStudy (anonymous):

oh man now i see what i did wrong lol

OpenStudy (anonymous):

so its 12.1

OpenStudy (anonymous):

So 4^2 + h^2 = 13^2

OpenStudy (anonymous):

I don't have a calculator but if that is the squareroot of 153 then yes you r correct

OpenStudy (anonymous):

thanks the answer to the whole question is 163.89 in ^3

OpenStudy (anonymous):

Sounds about right again that's a guess because I have no calculator
