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.
In this chapter we examine the derived units for volume and density. Volume. The volume of a cube is given by its length cubed, (length) 3. Thus, the basic SI unit of volume is the cubic meter, or m 3, the volume of a cube that is 1 m on each edge.Smaller units, such as cubic centimeters, cm 3 (sometimes written as cc), are frequently used in chemistry.n this chapter we examine the derived units for volume and density.
