The moment of inertia is calculated three different ways, about the center of the I height, I width and about the end I length directions: Z-axis, Y-axis and X-axis, respectively. For the purposes of this calculation, a cube can have three equal sides or it can have three non-equal sides. Fundamentally, the moment of inertia is the second moment of area, which can be expressed as the following: I x y 2 d A. This calculation is for the moment of inertia of a cube.
