Final answer:
A board foot measures 1 inch thick by 12 inches wide by 12 inches long. It is a standard unit of measurement in lumber that corresponds to volume. To convert feet to inches or the other way around, multiply the number of feet by 12, the number of inches in one foot.
Step-by-step explanation:
A board foot is a unit of measurement used in the lumber industry. It refers to a piece of wood that measures 1 inch thick by 12 inches wide by 12 inches long. The calculation of board feet is useful when purchasing or selling wood, as it reflects the volume of lumber.
To understand the concept, think about how units of measurement are used for various lengths and sizes. For example, feet are commonly used instead of inches to measure larger objects. To give you an idea, the length of a car, the height of a door, or the distance between two points can all be measured in feet because a foot consists of 12 inches.
When setting up a proportion to convert between units, such as converting feet to inches or vice versa, the concept of unit equivalence becomes significant. For instance, 1 foot equals 12 inches. If you have a measurement in feet and you need to find its equivalent in inches, you simply multiply the number of feet by 12. For example, 10 feet is equivalent to 120 inches because 10 times 12 equals 120.
