a 7. The area of the base of a hexagonal pyramid is \( \frac{24}{\tan 30^{\circ}} \mathrm{cm}^{2} \). Find its volume. to the nearest tenth.

Step 1 ：1. Calculate the area of the hexagonal base: \( A = \frac{24}{\tan 30^{\circ}} \mathrm{cm}^{2} \)

Step 2 ：2. Express the volume of the hexagonal pyramid: \( V = \frac{1}{3} Ah \mathrm{cm}^{3} \)

Step 3 ：3. Solve for h in the volume equation, and round to the nearest tenth.
