Hubber’s Formula (for Paraboloid...

The volume of the log will be calculated using quarter girth formula

*V* = (g/4)^{2} * *l*

π of value 3.14 is approximated to 4. Thus this formula underestimates the volume almost 21.5% as compare to full circular volume. It is known as Hoppus’ Formula in Britain. Even if the log had no taper, the volume of the square timber would be 2*r*^{2}*l*.
