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)?
