Final answer:
The object has a fractal dimension of 3, suggesting it is a fractal.
Step-by-step explanation:
To find the dimension of the object, we can use the concept of fractal dimension. In this case, when the length of the ruler is reduced by a factor of 2, the number of elements increases by a factor of 8. This indicates a self-repeating pattern, which is a characteristic of fractals.
Fractal dimension is a measure of how space-filling a pattern is. It can be calculated using the formula:
d = log(N)/log(S)
Where d is the fractal dimension, N is the number of elements, and S is the scaling factor. In this case, d = log(8)/log(2) = 3. This means the object has a fractal dimension of 3, which suggests it is a fractal.
