I need 400 brackets made that have parts a 57 5/8"  length of 2" x 3" angle,   

$${\mathtt{400}}{\mathtt{\,\times\,}}\left({\mathtt{57}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{5}}}{{\mathtt{8}}}}\right) = {\mathtt{23\,050}}$$   inches           $$23050/12 = 1920' 10"$$

 

a 96 3/16 piece of 2" x 2" angle

$${\mathtt{400}}{\mathtt{\,\times\,}}\left({\mathtt{96}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{3}}}{{\mathtt{16}}}}\right) = {\mathtt{38\,475}}$$   inches           $$3206/12 = 3206' 3"$$

 

and a 65 1/4" piece of 1"x 1 angle.

$${\mathtt{400}}{\mathtt{\,\times\,}}{\mathtt{65.25}} = {\mathtt{26\,100}}$$    inches                $$26100/12 = 2175'$$

 

What is the total lengh to 2"x 3" angle needed?     

How many inches of 2"x2" angle are needed?

How many inches of 1"x1" angle are needed?

 

If I understand you question properly
