1. Calculate the area of one small square:
\text{Area of one small square} = \frac{256}{64} = 4 \text{ square inches}
2. Set up the equation for the side length of the small square:
x^2 = 4
3. Solve for \( x \) by taking the square root:
x = \sqrt{4}
4. Therefore, the side length is:
x = 2
Thus, the dimensions of each small square are 2 inches by 2 inches.
