1. The problem requires the lumber quantity to be an integer value. 2. Let's assume the previous question involved calculating the amount of lumber needed as a number, possibly a decimal or fraction. 3. To satisfy the integer requirement, we round or adjust the lumber amount to the nearest integer. 4. If the lumber amount is a value $x$, then the integer lumber quantity is $\text{round}(x)$ or $\lfloor x \rfloor$ or $\lceil x \rceil$, depending on rounding context. 5. Without the exact previous question, we conclude that the lumber must be an integer and suitable rounding or ceiling/floor functions should be applied to ensure an integer quantity. 6. Therefore, the solution is to select an integer lumber quantity by rounding the previously computed value accordingly.
