The amount of space something takes up Liquids are measured in
milliliters (mL) Solids are measured in cubic
centimeters (cm3)▪ For a regular solid such as a cube , measure
the length (l) the Height (h) and the width (w). Then multiply l x h x w to get the volume
▪ For an irregular solid use the water displacement method using a graduated cylinder
