Square feet of Area ..is ?..L x W plus Weight of sq feet gives you what is weighs right?
Answer:
459.18lbs
139in*35.5in=4934.5 sq.in
4934.5 sq.in / 144 sq.in = 34.27 sq.ft
34.27 sq.ft * 13.4 lbs/sq.ft = 459.18 lbs
First of all, 3/8" plate weighs 15.3 psf, not 13.4. Take a piece of plate 12" sq by 3/8" thick. The volume of the plate is 12*12*3/8 = 54 cubic inches or 0.03125 cubic feet. Steel has a density of 490 pcf. therefore this piece weghs 490* 0.03125 = 15.3125 psf.
a piece of steel that is 139 x 35.5 x .375 = 1850.4375 cubic inches or 1.070855 cubic feet. For a density of steel at 490 pcf, this piece of steel weighs 524.7 lbs.
The area is 139 x 35.5 = 4934.5 sq inches = 34.267 sq feet
At 15.3125 psf this piece of steel weighs 34.267*15.3125 =
524.7 lbs.
However gave you that value orf 13.4 is incorrect.
Area of plate = 11.6ft x 2.96ft = 34.32 ft²
Total = 34.32 x 13.4 = 459.84lbs. (460lbs)
