What is the total board footage for a four-quarters board that is 4.25 inches wide and 11 feet long, adding 10% waste?

To find the total board footage for the given four-quarters board that is 4.25 inches wide and 11 feet long, including an allowance for waste, the calculation must follow these steps:

1. Convert the width from inches to feet: Since board footage is typically calculated using feet, start by converting the width. There are 12 inches in a foot, so:

[

\text{Width in feet} = \frac{4.25 \text{ inches}}{12} \approx 0.35417 \text{ feet}

]

2. Calculate the board footage without waste: The formula for board feet is:

[

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

]

Here, the thickness for a four-quarters board is typically considered as 1 inch, so:

[

\text{Board Feet} = 0.35417 \text{ feet} \times 11 \text{ feet} \times \left(\frac{1}{12}\right) \approx 0
