Aight, let’s do some number crunching.
The average two by two lego brick which is used here is about 15.8 mm on width and length, and 9.8 mm high.
An estimation leads me to believe that a brick in the animation is 10 bricks wide, long, and 12.40506329113924 (round to the nearest number, it equals 12) bricks high.
12 x 9.8 = 11.76 cm
20 x 15.8 = 31.6 cm
By the fifth stage, a single brick would be:
31.6 meters long and wide, as well as 11.76 meters high.
The entire structure at the fifth stage, however, would be:
636 meters long and wide, and 141 meters tall. For reference, this would be slightly smaller size than your mom.
