Question 1210140
.
The  base of right pyramid ABCDE is a rhombus with side 5. We also know that triangle ABD 
is congruent triangle CBD and EA=BA=2. Find the volume of the pyramid.
~~~~~~~~~~~~~~~~~~~~~~~~



This post is a mess and gibberish.  It describes a situation which NEVER may happen.



                        Below I explain WHY.



The problem says that the base of the pyramid, a quadrilateral ABCD, is a rhombus with the side 5.
Then in the next statement, the problem says that BA=2.


But BA is the side of the rhombus, and its length is 5, as described in the previous statement.


So, this post is illogical.


A right place for it is the closest garbage bin.
