I assume you're working on a deck or floor. Determining ft2 depends on how the lumber is laid.

If it was laid 3" side up (horizontal), the ft2 of each 6 ft piece would be: (3"/12")*6 ft = 1.5 ft2.
If it was laid 2" side up (horizontal), the ft2 of each 6 ft piece would be: (2"/12")*6 ft = 1.0 ft2.

If a floor was 13 ft x 10 ft and the lumber was laid with the 3" side up (horizontal): 130 ft2 / 1.5 ft3 = 87 (86.67) pieces of 2" x 3" lumber 6 ft long. No scrap is assumed.
