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.
What is volume? Volume is a measure of how much space an object takes up. For example two shoe boxes together have twice the volume of a single box, because they take up twice the amount of space. Different shapes have different ways to find the volume. For example, in a cube we find the volume by multiplying the three side lengths together.
