C & C cage question. Can anyone help?

I'm building a C&C cage for my guinea pigs. I am going to use a fleece bedding inside but i don't know how much to buy. It is 2 grids by 5 grids, 10.5 square feet, with inner meausurements of 30 inches by 62 inches. The fabric comes in yards that are 58" wide. It would be great if someone could help! Thanks :]
