The moment of inertia of a triangular section of height h about an axis passing through its C.G and parallel to its base is given as,
I = bh3/36.
The moment of inertia of a triangular section of height h about its base is given as,
I = bh3/12.
I = bh3/36.
The moment of inertia of a triangular section of height h about its base is given as,
I = bh3/12.

I = bh3/12 for triangular section oh height h about its base, and centroid of triangular section is given by 1/3.
So I = bh3/12*1/3. Which is bh3/36?
So I = bh3/12*1/3. Which is bh3/36?
