\question[1]These are some examples of numerical problems. A 1\si{\kilo\watt} load runs continuously for one day. Find the total energy drawn in \si{\kilo\joule}. \begin{solutionorbox}[2in] Total Energy = Power x time\\ $=1\si{\kilo\watt}\times24\si{\hour}$\\ $=1000\si{\watt}\times24\times60\times60\si{\sec}$\\ $=86400\si{\kilo\joule}$ \end{solutionorbox}
