Calculation formula of K-type ordinary prefabricated house: (by floor)

1k=1.82m (2k is one room)

1、 Calculation formula for area of single storey ordinary prefabricated houses

① The main area of the plank house = outer side length * outer side width, that is (mk+0.16) * (nk+0.16), k=1.82 meters, m, n is a natural number above 2.

② Canopy area =0.5 * 1m * outer side length (projected area of 1m) or 0.5 * 2m * outer side length (projected area of 1.2m).

③ Total area = ① + ②.

2、 Calculation formula of area of double-layer common movable plank house

① The main area of the plank house =2* outer side length * outer side width, that is, 2* (mk+0.16) * (nk+0.16), k=1.82 meters, m, n is a natural number above 2.

② Canopy area =0.5 * 1m * outer side length (projected area of 1m) or 0.5 * 2m * outer side length (projected area of 1.2m).

③ Walkway area =1* outer side length (the width of walkway projection is 1 meter), that is, 1* (nk+0.16).

④ Stair area =n*4.5 square meters, n is the number of stairs.

⑤ Total area = ① + ② + ③ + ④.
