Identify the intersection of plane abd and plane cde

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

hope this is what you were asking for!
