1 For the first time in 20 years, federal health authorities have lowered the recommended limit for lead exposure in young children, which they say could add 200,000 children to those believed to have unsafe lead levels in their blood.
The volume can be measured in cubic meters, cubic centimeters, or liters. The units of the three-dimensional volume depend on the units of length-if the lengths are in meters, the volume will be in cubic meters, etc. To measure a square or cube: Volume = length times width times height.
When measuring a small liquid volume, such as a dosage of cough medicine, the best unit to use is milliliters or ounces. A slightly larger volume, like the amount of flour or sugar needed to make cookie dough, would be measured using cups. A liquid volume of this size, like heavy cream, would be measured using pints, milliliters, or liters. The volume of a bigger amount, like a bottle of apple juice or soda pop, can be measured using liters and quarts. A really big liquid volume, like an aquarium or swimming pool, would be measured in gallons or liters.
