(Solved): Perform the following conversions: \[ \begin{array}{l} 8.4 \mathrm{ft}^{2} \text { to } \mathrm{cm} ...

Perform the following conversions: \[ \begin{array}{l} 8.4 \mathrm{ft}^{2} \text { to } \mathrm{cm}^{2} \\ 223 \mathrm{mi}^{2} \text { to } \mathrm{km}^{2} \\ 231 \mathrm{ft}^{3} \text { to } \mathrm{cm}^{3} \end{array} \] Part 1 Choose the proper equation to convert between \( \mathrm{ft}^{2} \) to \( \mathrm{cm}^{2} \). \[ \begin{aligned} \mathrm{cm}^{2} &=\left(\mathrm{ft}^{2}\right)\left(\frac{30.48 \mathrm{~cm}^{2}}{1 \mathrm{ft}^{2}}\right) \\ \mathrm{cm}^{2} &=\left(\mathrm{ft}^{2}\right)\left(\frac{30.48 \mathrm{~cm}}{1 \mathrm{ft}}\right)^{2} \\ \mathrm{~cm}^{2} &=\left(\mathrm{ft}^{2}\right)\left(\frac{1 \mathrm{~cm}}{30.48 \mathrm{ft}}\right)^{2} \\ \mathrm{~cm}^{2} &=\left(\mathrm{ft}^{2}\right)\left(\frac{1 \mathrm{~cm}^{2}}{30.48 \mathrm{ft}^{2}}\right) \end{aligned} \]
