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...)
