What's heavier by volume... sand or water?

[Phokus]

I'm asking cuz i just bought this free standing punching bag http://www.amazon.com/exec/obidos/tg/de...115?v=glance&s=sporting-goods&n=507846

and i want it so the base is as heavy as possible and it doesn't get knocked over or move around when i'm punching the bag.

thanks.

sand.

does sand float? Duh. It must be denser than water.

water = 1000kg/m^3

sand = generally over 2000kg/m^3

Soil mechanics is your friend

A pound of sand is heavier than a pound of water.

Huh?

A pound of anything is the same weight equivalent as a pound of anything else. :roll:

Sand is a better idea anyways...leaking sand isn't as bad as leaking water.

Also when sand freezes it doesn't expand.

*sigh* Lets not get into density discussion involving pressure. Surely the OP wanted a practical answer that. If you want to get technical, there is Highly Technical forum. :frown:

Your best bet is to self experiment.

Fill a Gallon Jug w/ water.
Fill a Gallon Jug w/ sand.
Weigh.

I'd be willing to bet a gallon of sand is heavier.

I wasn't going to go that far; it isn't needed and is way over the head of most in OT Just simple facts that a lot of people overlook. gold is measured in troy ounces, and a troy pound is 12 ounces. Therefore 16 imperial ounces of feathers > 12 troy ounces of gold. Also, a troy ounce is a little more than a imperial pound.

that would be a good riddle.
