6. Find the volume of a hexagonal pyramid with a base area of \( 25 \mathrm{ft}^{2} \) and a height of \( 9 \mathrm{ft} \).

Step 1 ：\( V = \frac{1}{3}Bh \)

Step 2 ：\( V = \frac{1}{3}(25\mathrm{ft}^{2})(9\mathrm{ft}) \)

Step 3 ：\( V = \frac{1}{3}(225\mathrm{ft}^{3}) \)

Step 4 ：\( V = 75\mathrm{ft}^{3} \)
