I was watching this Japanese game show and came across this question:
The contestants were told that each small cube is 2cm on its side and were asked to find the volume of the above figure.
The answer was 3080 $cm^3$.
While I was counting the number of cubes for the first row, one of the contestants was able to answer this within a few seconds.
I'm curious about how he did it. I assumed the figure was constructed in some sort of pattern and was hoping someone could shed some light on this.
(The game show didn't explain how to solve this unfortunately...)
