What's the best combination of weight, cost, size and availability?

I want to make a small (8" x 8") piece of plywood very, very heavy by affixing something to the top of it. It could be a single solid object, or a container filled with a very heavy particle (sand, metal pellets, whatnot). The weight on top of the plywood can be up to 4" in height but no higher. I'd like to do this as cheaply as possible. What will give me the best combination of (a) weight, (b) cost to purchase, (c) availability and (d) size?
