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.
Any unit of length gives a corresponding unit of volume, namely the volume of a cube whose side has the given length. For example, a cubic centimetre (cm 3) would be the volume of a cube whose sides are one centimetre (1 cm) in length.n the International System of Units (SI), the standard unit of volume is the cubic metre (m 3). The metric system also includes the litre (L) as a unit of volume, where one litre is the volume of a 10-centimetre cube.
