Clyde is building a work bench 16' long that will require four brackets to make it stable. Using the diagram, determine the total length of angle iron needed to support the work bench and calculate the COST of the angle iron. • 1 1/2" x 1/4" angle $1.44/ft. • 3" channel iron $1.75/ft. • 1/4" x 3" flat bar $0.98/ft. • 4" channel iron $2.10/ft. • 3/8" x 1 1/2" flat bar $0.75/ft.
