In 2 of the 4 estimates for a new furnace for here in Southwest PA, the answer is yes. This house is a Cape Cod style and was built in 1950. But then 2 said I'd need over 100,000. So I'm wondering too!
I am assuming you mean 80,000 output, not input. An 80,000 input rated at 80% efficiency only has an output of 64,000. A 95% efficient 80,000 input will give you 76,000 output. Go with the people who did a proper heat loss calculation on your home since any two 1800 square foot houses could have different heating/cooling requirements. You also don`t want to oversize either. When I replaced mine 3 years ago I went from 100,000 to 52,000 and those are the input ratings at 80% & I`m doing just fine.
(1800-1200)/1800 * 100 = 600*100/1800 = 600/18 ~= 33.33 %
1% of 1800 = 1% * 1800 = 0.01 * 1800 = 18
30% of 1800= 30% * 1800= 0.30 * 1800= 540
75% of 1,800= 75% * 1800= 0.75 * 1800= 1,350
As 1800, exactly as it appears in the question.

1800 square feet is equal to 1672254.72 square centimeters.
Because 1 foot equals about 0.3048 meter then 1800 square feet equals (0.3048 meter) (1800) = 548.64 meters
there is 200 squared yards in 1800 squared feet 9/1800=200 squared yards

1800 x $18.00 = $32,400.
Answer: 1800 m² = 19375.038 ft² OR 19375 ft² and 5.58 in²
