Q.Composting not fast enough
I have lots of shredded cardboard and wondered if it would be okay to put it on my 40’x60′ garden. Would it be okay to do this without composting it first? I have been composting as much as I can but still have a many bags full.

If the cardboard is shredded pretty well and fine and is free from tape, staples, ink, plastic, and Styrofoam, yes--you can put in your garden. At that stage though it will serve more as mulch rather than compost. Some people mix it in with the garden soil.
