Okay, so I am expanding the cage from a 2x3 to a 3x4 and I was wondering how much coroplast I would need for that, I was planning on still keeping the coroplast from the old cage and taping it with the new (does that make sense??) so how much more coroplast would I need for that? I originally had a 4x8 sheet and cut out enough for the 2x3. And how many more grids would I need? AND, how many grids would I need for a stand? Sorry there is sooo many questions, I am absolutely HORRIBLE at math
