The volume expansion of a solid is given by $\Delta V = V_0 \beta \Delta T$, where $\beta = 3\alpha$ for isotropic materials (like steel), $\alpha$ is the coefficient of linear expansion, $V_0$ is the initial volume, and $\Delta T$ is the temperature change. Given $\alpha = 11 \times 10^{-6} / ^\circ C$, $V_0 = 100 \, cm^3$, and $\Delta T = 100^\circ C$, we find $\Delta V = 100 \times 3 \times 11 \times 10^{-6} \times 100 = 0.33 \, cm^3$. Thus, the new volume is $100 + 0.33 = 100.33 \, cm^3$.
