In order to solve this, we must first find the total thermal resistance ($R_{total}$). The thermal resistors (copper, insulator 1, and insulator 2) are acting in parallel. Thus the total resistance is give by the following equation: ${\frac{1}{R_{total}}}={\frac{1}{R_1}}+{\frac{1}{R_2}}+{\frac{1}{R_3}}+...+{\frac{1}{R_n}}$ where ${R_n}={\frac{L}{k_nA_n}}$ ...
