For the regular square pyramid shown, suppose that the sides of the square base measure \( 18 \mathrm{ft} \) esch and that the altitude is \( 12 \mathrm{ft} \) in length. (a) Find the lateral area \( L \) (in square feet) of the pyramid. \[ L=x \mathrm{ft}^{2} \] (b) Find the total area \( T \) (in square feet) of the pyramid. \[ T=x \mathrm{ft}^{?} \] (c) Find the volume \( V \) (in cubic feet) of the pyramid. \[ V=\quad x \mathrm{it}^{3} \]
