Help, I still cannot wrap my head around this

atroni [7]

Answer:

9 inches.

Step-by-step explanation:

Fun question! The length of a space diagonal for a cube is $\sqrt{3*sidelength^2}$

Thus, the first cube has a side diagonal of $\sqrt{3}$

The next cube would have a side diagonal of 3

The third cube would have a side diagonal of $3\sqrt{3}$

And the fourth cube would have a side diagonal of 9.

Since the fifth cube has a side length equal to the side diagonal of the fourth cube, it should be 9 inches.
