Yes, a W-8X18 will carry the weight of a basement load wall 2X6 over a 200 feet span.
You can get more insulation when using 2x6 studs rather than 2x4 studs
Laminating 2x6's is a much better idea, it won't twist like a PT 6x6, it is less expensive, and you can use a combination of lumber. I built a 24x 40 ' barn a few years ago for a woodworking shop. I used 4 pieces of 2x6, this gave me a doubled space at the top to slide in laminated doubled 2x12's ... I used 0.40 PT lumber at the bottom and regular KD above, I laminated the bottom with staggered board lengths... I used a 12, 10 and two 8 footers, I needed an 18 ' post to have 4' in ground and 14' above. I also used stainless steel nails below ground and regular above, a nail gun sure was handy. After the posts were in, I drilled holes and used a 6 inch 3/8th carriage bolt to reinforce the connection. I overbuilt my barn, went 8' on center, not 12'. Also I used a doubled 2x14 glue lam 40' long for the ridge, that way the building was clear span and I didn't put up collar ties. I used a regular plywood roof and shingles. I used one inch rough cut shiplap pine boards for vertical sheathing, came out nice.
you didn't say how large the floor was but you should be able to install new 2x6 joist supporting mid ro third span as required bobp
You must also take in consideration the width of the building. For instance a 12'x16' building you would use 2x6 rafters and a 2x8 beam with collar ties every 4'.
A 2X6 (dry Douglas fir) weighs 2lbs per foot. Thus a 20ft 2X6 would weigh 40 lbs. Other types of lumber such as pine weighs more and all lumber is heaver when wet or if it has been treated.
1 1/2"x 5 1/2"
2x4, 2x6 and 2x10
you build forms,lay in rebar,pore concrete,put in J bolts,to bolt your 2X6 pressure treated wood to.then floor joists.
Lumber yards and home improvement stores in the U.S. generally stock stud length 2x6's (92-5/8").
A 2X6 is 5 1/2 inches wide. Incidentally it's 1 1/2 inches thick. Pre-WWII lumber was cut at stated dimensions, a 2x4 was actually 2 inches by 4 inches.

For 2×4s of any size, it is 294 pieces of lumber. A "bunk" is a collective quantity for shipped lumber, and each size of lumber has a different quantity for a specific type of wood.. 2x4 = 3 x 7 x 14 (294) 2x6 = 3 x 7 x 9 (189)
A saw mill rough cuts a log into standard sizes of lumber such as 2x4, 2x6, 2x8,etc. The rough cut lumber is cut to the actual measurements of 2" x 4", 2" x 6", 2" x 8", etc. The lumber at this point is very rough so it is run through a planner that smoothes the lumber by removing a small amount of wood on each of its four sides. The actual dimensions of the lumber after being smoothed is 1/2" smaller in both width and thickness so a 2x4 will actually measure 1 1/2" x 3 1/2", a 2x6 is 1 1/2" x 5 1/2", a 2x8 is 1 1/2" x 7 1/2", etc. A 2x6 bought by a consumer at a lumber yard is actually only 1 1/2" or 1.5" thick and 5 1/2" or 5.5" wide. A 1 foot (12") length of 2x6 is (5.5" x 12") 66 square inches. 64 square feet is equivalent to (64 x 12" x 12") 9,216 square inches. So it takes (9,216/66) 139.64 feet of 2 x 6 to cover 64 square feet. Ten 2x6's 14 feet long will cover almost exactly 64 square feet.

It depends on where you live. If you are in a colder climate the up front cost of the 2x6 lumber will pay off over time. The extra insulation will be worth it.
