3 bundles per square (a square is 100 Sq. ft.) 18 sq. in 1800 sq. ft. so 3x18=54. Add a few bundles for the starter course and the ridge cap. No way to figure these here without knowing the size and shape of the roof. Felt 15 lb. covers 400 sq.ft. per roll and 30 lb. covers 200 sq. ft. One is twice as thick and usually this is personal preference or a cost issue. Either will do the job in most cases.
It depends on the required overlap. In the UK its 66% (or two thirds on clay tiles so it would be 1260 x 1.66 = 2091 sq feet of tiles.
Every sixth row should be nailed.

When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.

Tough question because an 1800 sq' home has more than 1800 sq' of roof coverage, unless it has a flat roof. In which case, shingles would not be the material of choice. You need to measure the foor deck itself; either by measuring the gutter and rake (gable) edges to find square footage or, figure the pitch of your roof and calculate from there. You also have to factor in any other roof linrs such as hip roofs, shed or gable dormers, etc.. But if your roof was, in fact 1800 sq' you could figure the bundles by knowing that 3 bundles typically cover 100 sq' sooo...100/1800=18; 18x3=54
12 x 12 tiles cover 144 ft2, so the number of tiles needed is 1800/144, which equals 12.5.
In the 1800's, railroad companies raised the money they needed by selling government land grants.
one of its uses was to cover unpleasant odors
1800/10 = 180

Chlidren were forced to work in the 1800's because they were poor, and they needed to take care of their families
You convert everything to compatible units. Then you multiply area x depth. I suggest you convert the depth to feet; in that case, the answer will be in cubic feet.
