Can be eight or eleven feet long.
In actuality, it can be as long as you want. 2x4 refers to the width and height dimensions of the plank, not the length. So I could cut a 2x4 to 2 inches long and it would be a 2 inch long 2x4.
You will need at least 13-9' 2x4's, on 16" centers, and 2-16' 2x4's for plates. (Deduct plate thickness from stud length)

To frame a space of 240 square feet, you'll need to calculate the perimeter and the amount of framing required. Assuming standard wall height and no windows or doors, you can estimate that you will need approximately 1 linear foot of 2x4 for every square foot of wall area. This means you would need about 240 linear feet of 2x4. Since a standard 2x4 is 8 feet long, you would require around 30 pieces of 2x4 (240 ÷ 8 = 30).

20x20 = 400 2x4= 8 400/8= 50 needed
For 2x4 framing, it is recommended to use 3-inch long screws.
2x4-56 2x4=8 8-56= -48)

Yes.

2x4x20/12= 13.33 bdft.
2x4 does not equal 7, it equals 8. 2x4=8 is a correct statement.

Yes, a jigsaw can cut a 2x4.
Yes, you can cut a 2x4 with a jigsaw.
A "board foot" is 1 inch thick, 12 inches wide, 12 inches long. A 12 ft 2x4 would be 8 board ft- 1/3 the width, but 2X the thickness.
