What is the number of board feet of lumber for 25 - 2x12's, 30 feet long?

  1. 2,000

  2. 1,500

  3. 3,000

  4. 700

The correct answer is: 1,500

To determine the number of board feet of lumber in 25 pieces of 2x12 lumber, each 30 feet long, one needs to understand how to calculate board feet. A board foot is defined as a volume of 1 foot long, 1 foot wide, and 1 inch thick. The formula to calculate board feet is: Board Feet = (Thickness in inches x Width in inches x Length in feet) / 12. In this case, the lumber is 2 inches thick (2x12), 12 inches wide, and 30 feet long. Plugging in these values: Board Feet = (2 inches x 12 inches x 30 feet) / 12 = (720) / 12 = 60 board feet for one piece of 2x12 lumber. Since there are 25 pieces, the total number of board feet is: Total Board Feet = 60 board feet/piece x 25 pieces = 1,500 board feet. Thus, the total amount of lumber for this scenario is 1,500 board feet. This calculation illustrates how to use the board feet formula effectively in practical applications of lumber measurement.
