silverdiv......you are talking to the crock pot expert. You really want to cook your roast on low but if you have to cook it on high depending on the size of the roast it usually should take 3-4 hours.
The symbol for cubic meters is m 3. Less formally, cubic meter is sometimes abbreviated cu m. When calculating volume, it is important to realize that volume is proportional to the cube of the linear dimension.
A cubic centimeter is a unit of volume accepted and widely used in the countries recognizing the SI standards. This unit is corresponding to the volume equal to the one of a cube with 1 cm each side. Therefore, one cubic centimeter is equal to 1/1 000 000th of a cubic meter. It is also roughly equal to 1 ml, or 1/1000th of cubic liter. The symbol of a cubic centimeter is cc, and this volume unit is very widely used in such fields as medicine, engineering, technology, etc.
