for a total of 1,170,403.6390cm^2 x tensile strength of sandstone 25 Megapascals or 2500 N/cm^2 = 2,926,009,097.5162 Total Newtons


diagonal of the building is (a^2 +b^2 = c^2 ) 4245.9168cm x 104.2541cm thickness of white sandstone x 2 for both wall = 885,308.4693cm + the 376,303.8082cm^2 = 1,261,612.2775cm^2 x tensile strength of sandstone 25 Megapascals or 2500 N/cm^2 = 3,154,030,693.75N

but is our low end for the durability of the Sword steel


the high end is as both their blades clashed orthogonality to each other the contact area would be defined by the thickness of each blade or 1micron by 1 micron which is equal to 0.000,000,001 cm^2 which equals 315,403,069,375,000,000N/cm^2 or 31.54 ZettaPascals city level durability
