How many pounds of sand for a 10gallon tank?

hmm....i guess i just figured that because it was sand it would require more....now i need to find out what to do with 25 pounds of sand....

make a mini sandbox and mount it to your wall just below a window. go to walmart and pick up as many little monster trucks as you can and have a midget monster truck rally in your living room. if you have small boys they'll love one in their room too.
 
Use it to break up any compacted areas in your garden/flowerbeds.
