To determine the number of board feet in a piece of lumber, you can use the formula:

**Board Feet = (Thickness in inches x Width in inches x Length in feet) / 12.**

In this case, the dimensions are 2 inches (thickness), 12 inches (width), and 24 feet (length).

First, you multiply the dimensions together:

2 inches x 12 inches x 24 feet = 576.

Then, you divide by 12 to convert the cubic inches into board feet:

576 / 12 = 48 board feet.

This calculation shows that the correct answer is 48 board feet. Understanding this formula allows you to calculate the volume of lumber accurately and is a vital skill in real estate and construction contexts where lumber is a primary material.
