Hello Mike!

This question is from the blue book test 1 section 3 #19

The pyramid shown above has altitude h and a square base of side m. The four edges that meet at V, the vertex of the pyramid, each have length e. If e=m, What is the value of h in terms of m? I tried plugging in the value for e=6. Then if we form a triangle out of the figure, we get the hypotenuse as 6, the side below as 3. So shouldn’t this be a 30-60-90 triangle? Then h would be 3root3 and then the answer A)?

Thank you

I’ve done this one before–don’t forget to check the Blue Book Solution Links before you ask Blue Book questions. I’ve done most of the tough questions in the Blue Book already. 🙂
