Let the large cube have sides with length 3
This means the volume of the large cube = (3)(3)(3) = 27

This means a small cube will have sides with length 1
So, the volume of the small cube = (1)(1)(1) = 1

What approx % of the total volume is one of the small cubes?
We need to convert 1/27 to a percent.
NOTICE that 1/25 = 4%
So, 1/27 to a percent will be a little bit smaller than 4%
Only one answer choice meets that condition.
