Without finishing, the materials cost about 1.80 per square foot. Labour depends how fast you are.
It takes 2x4 's in wood or metal and drywall to cover it. Possibly insulate it, depending on the intended use.
You use 5/8 fire proof drywall on both sides.
Paper drywall tape is the same both sides.
alot of money.
The number of sides and the number of interior angles are the same.
In the U.S., in most cases, the framing for both interior and exterior walls is 2x4 dimensional lumber with an actual dimension of 1-1/2 inches x 3-1/2 inches. With 1/2" drywall on both sides, a finished interior wall will be 4-1/2" thick. With drywall on one side, and 1/4-3/4" exterior sheathing on the other side, an exterior wall will vary in thickness. Siding, stucco, or brick veneer will add to the exterior wall's total thickness.
If the interior angles add up to 4320 degrees then it will have 26 sides
If each interior angle measures 176 degrees then it will have 90 sides
It has 180 sides if the interior of the (regular) polygon has a total of 178 'degrees'.
If it is a regular polygon and each interior angle is 176 degrees then it will have 90 sides.
Because; (number of sides-2)*180 = sum of interior angles
sum interior angles = (number of sides - 2) × 180° → number of sides = sum interior angles ÷ 180° + 2 = 5040° ÷ 180° + 2 = 30
