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.
The derived SI unit for volume is the cubic meter or m3 based on the three dimensional use of the base unit for length, the metre. The more common metric unit for volume is thâ¦e litre, which has been defined since 1964 as dm3 (mathematically equal to 1000 cm3).
