To build a 20 ft ramp, you will need **349.090909091 pieces** of 2x6 lumber. Each piece of 2x6 lumber is 6 ft long. Here's the breakdown:
1. **Calculate the total area of the ramp**: The ramp has a length of 20 ft and a depth of 1 ft, so its area is 20 ft x 1 ft = 20 sq ft.
2. **Calculate the area of one 2x6 board**: A 2x6 board is actually 1.5 inches by 5.5 inches in nominal size. Converting inches to feet, its area is (1.5/12) ft x (5.5/12) ft = 0.0572916666667 sq ft.
3. **Calculate the number of boards needed**: The number of 2x6 boards required is the total ramp area divided by the area of one board, which is 20 sq ft / 0.0572916666667 sq ft = 349.090909091 boards.
4. **Calculate the total length of boards needed**: The total length of 2x6 boards required is the number of boards x length of each board = 349.090909091 boards x 6 ft/board = 2094.54545455 ft.
So, you need 349.090909091 pieces of 2x6 lumber, each 6 ft long, to build a 20 ft ramp.
