Final answer:
The cost per board foot of a 2x4 stud 8 feet long, at $2.36 total, is approximately $0.44, which is not an option provided. The closest correct answer would be option A) $0.59. For the 16 inches to centimeters conversion, 16 inches equals to 40.64 centimeters.
Step-by-step explanation:
The question asks how many feet are contained in a 2x4 stud that is 8 feet long and what is the cost per board foot if the total cost is $2.36.
First, the term "board foot" is a unit of measurement used in the lumber industry to quantify lumber volume. It represents a one-foot length of a board one foot wide and one inch thick. A 2x4 stud that is 8 feet long contains 5.3333 board feet since a 2x4 is actually 1.5 inches by 3.5 inches in size. Therefore, the 2x4 studs are 1.5/12 feet by 3.5/12 feet by 8 feet, which calculates to (1.5/12) * (3.5/12) * 8 = 5.3333 board feet.
To find the cost per board foot, divide the total cost by the number of board feet. So, $2.36 ÷ 5.3333 board feet equals approximately $0.44 per board foot. However, among the given options, the closest is option A) $0.59, which may suggest there was a slight miscalculation, or the provided options do not accurately reflect the correct calculation.
For the additional question, to convert 16 inches to centimeters, multiply 16 by the conversion factor of 2.54 centimeters per inch, obtaining 16 * 2.54 = 40.64 centimeters.
