6. A welder is building the storage container shown below with sides, bottom and center divider made of 10-mm plate steel. Use the steel design table in the appendix to calculate the weight of the box, rounded to the nearest kilogram. 14 m 8 m 3m Name Rectangle Parallelogram Trapezoid Triangle Circle Sector Ellipse Figure b L L W Perimeter/Circumference P=2L+2W P=2a + 2b Add all four exterior lengths Add all three exterior lengths C=2r **for a circle, perimeter is renamed circumference since it is the measure of a curve L= 180 **for a sector, perimeter is renamed arc length C=n(a+b)) |j=1+h+ +26 + (a-b) (a+b) Area (A) A=LW A=bh 1 A==h(a+b) A=-=-bh A= r nd A = this formula can be used if the diameter (d) is known instead of the radius 360 A-nab -r Sondrigare Geometry romanas.
