Its Young's (excluded) not Old's (included)

A cone of circular cross section having base radius $$R$$ and height $$L$$ and mass $$M$$ is suspended from its base as shown in the figure. The material of the cone has young modulus $$Y$$. The acceleration due to gravity is $$g$$. The elastic potential energy stored in the cone is $E=\frac{m^{a}g^{b}L^{c}}{d\pi^{e}R^{f}Y^{g}}$

Find $a+b+c+d+e+f.$
