To determine which description matches a board that contains exactly 10 board feet, we need to understand how to calculate board feet. One board foot is defined as a volume of lumber that is 1 foot long, 1 foot wide, and 1 inch thick. The formula to calculate board feet is:

[

\text{Board Feet} = \frac{\text{Length (in feet)} \times \text{Width (in inches)} \times \text{Thickness (in inches)}}{12}

]

Now, let's analyze the correct option. For the board described as being 10 feet long, 12 inches wide, and 1 inch thick:

1. Length: 10 feet

2. Width: 12 inches

3. Thickness: 1 inch

Using the formula for board feet:

[

\text{Board Feet} = \frac{10 \times 12 \times 1}{12} = 10 \text{ board feet}

]

This calculation confirms that this board indeed contains exactly 10 board feet, making it a match for the question.

The other options provide different dimensions that result in various calculations, which could yield different totals in board feet
