I honestly still don’t get what the question was asking. If a vertical line is moving horizontally on a 2d plane, how can it affect the area of a cross section of a solid thats 3D?
okay so i was a total idiot and used the y coordinate instead of the x for the intersection, but everything else was right but my answers were all wrong. do you think they’d give me any points for this question?
The last question was impossible

@@rohansharma9552 the vertical line is the same as the side of the cube (i think) so as the size changes, it changes the area of the square
After seeing part d I realized I could of got it if I didn’t freak out after seeing the words a vertical lining is moving thanks for the solutions!
8/9? I had everything except multiplying by 7 for part d which is a bummer. I literally had it in my calculator and didn't write it down:(
2/9

I think you'd get most of the points actually. Graders don't usually carry the same error forward to all parts.
