Question 1. Mia is connecting small cubes, adding one at a time to build a 3x3x3 cube.  She took pictures at 5 different moments, giving the 5 pictures shown below.  Which one is Mia's fourth picture?  Let's start off by looking at the option with the least amount of cubes.  D. Here we see that Mia has 4 cubes placed down. This would have to be the first picture.  Next we'll look at the next photo that she took with the next amount of most cubes,  which would be B. So that would be her second picture.  Next we see which one she adds onto, which will be option E. She's added all of these green cubes here, as shown, so that is the third picture. Next we have our options A and C.  We see that option C is the full cube. That'll be the fifth picture,  meaning that picture A will be our correct answer. That is the fourth picture, option A.

Video Summary

The process of determining Mia's fourth picture involves arranging the sequence of photos based on the increasing number of cubes. Starting with option D (4 cubes) as the first picture, then option B follows as the second picture with more cubes. Option E is determined to be the third picture after additional cubes are added. Finally, out of the remaining options, option C completes the 3x3x3 cube and is the fifth picture. Hence, option A, showing the penultimate addition of cubes, is identified as the fourth picture.
