Did you know .. . . By chris

Did you know that a thousands cube represents a liter capacity?
A tiny unit cube = 1 milliliter.

Show your students how you can pour a liter bottle of water into a liter cube.

If you weigh the liter of water it = 1 kilogram and and a tiny unit cube filled with water weighs one gram!

I made a liter cube out of laminated centimeter paper, taped all side and filled it with water but it doesn't last. You can buy liter cubes through most math/science catalogs.

Ask how many ml of a liquid would fill a tiny unit cube, a tens rod, a hundreds flat, a thousands cube?
How much would each of them weigh in g/kg?
