How many 2x6x16 i need on 1500 square feet?

To determine how many 2x6x16 boards you need for 1,500 square feet, first calculate the area covered by one board. A 2x6 board is actually 1.5 inches by 5.5 inches in dimensions, which translates to 0.5 square feet per board. To cover 1,500 square feet, you would need 1,500 / 0.5 = 3,000 boards.
