The stress$-$strain relationship for a material is given by $=2*{10}^5*{}^{0\mathrm{.}3}$ in MPa. Calculate the amount of energy to break the specimen of a $10cm10cm10cm$ specimen made of this material by dropping from a height of $100$ cm from the top surface of the material.

Assume the fracture strain, ${}_f=0\mathrm{.}25\%.$ Be aware that the energy needed to break the specimen is obtained by the multiplication of the modulus of toughness of the material and the volume of the specimen.
