$512$ board feet
RECALL: Number of Board Feet = $\dfrac{\text{number of boards} \times \text{thickness} \times \text{width} \times \text{length}}{12}$ where thickness, width, and length are all in inches. Using the formula above gives: Number of Board Feet $\\=\dfrac{24 \times 4 \times 4 \times 16 }{12} \\=\dfrac{6144}{12} \\=512$
