This is a cube with all edges measuring 26 mm. To calculate the volume of a cube, use the formula:

$\text{Volume} = \text{side}^3$

Here, the side length $s = 26 \, \text{mm}$. Substituting into the formula:

$\text{Volume} = 26^3 = 26 \times 26 \times 26 = 17,576 \, \text{mm}^3$

So, the volume of the cube is:

$\boxed{17,576 \, \text{mm}^3}$
