Kudos to
Sasindran - I used the approach for similar questions that do not involve volume. . . .
Next time I will notice if volume is involved.
Thank you.
But I feel that your method is a little “trial and error” method.
Sasindran , perhaps I was not clear. Or perhaps you misunderstood what I meant.
Your approach to this problem is vastly superior to mine. You were shrewd. I did not catch the algebraic connection. (Not good!)
And that meant I had to resort to finding the common side. I got lucky. As I mentioned, the numbers were easy. I will choose shrewd over lucky every time.
I put my method there for one reason only: I have seen questions where edge length must be found, and the only way to find edge length involves finding common sides. Those questions
look a lot like this one.
That was my mistake. Your good work taught me that I got complacent. Here, yours is by far the better way, IMO.
Nice work.
(And next time, at least from me, please assume the best. If I go out of my way to name you in a compliment, that means I am thrilled to see someone do well and grateful to have learned something.) Cheers.
