Is this board trash or is it repairable?

I bought a used 6’ foam board for 60$ the other day. I didn’t really get a good look at it when I picked it up but I notice now it’s got a lot of cracks and a few punctures on the bottom of the board. I’ve got a bunch of other boards but I bought this one just to have another soft top for the kids to use. Is this fixable or did I get swindled?
