To build a 20-foot wall with 2x4 lumber, you'll typically need to determine the spacing of the studs. If you space the studs 16 inches on center, you'll need about 15 studs for a 20-foot wall (20 feet = 240 inches; 240 inches / 16 inches = 15 studs). Additionally, consider any extra lumber for top and bottom plates, which would require approximately two 20-foot pieces of 2x4 for the plates. In total, you would need around 17-20 2x4s, depending on the design and any openings for doors or windows.
