VOLUME 1. Definition: * Volume is the amount of space an object takes up 2. Base Unit: * liquid volume = liter (L) * solid volume = cubic meter (m 3 )

8
LIQUID VOLUME 3. Instrument: * Liquid Volume - beaker, graduated cylinder, or a flask

SOLID VOLUME 3. Instrument: * Solid volume - metric ruler using the formula: L x W x H = V 3cm x 2cm x 4cm = 24cm 3

LENGTH 1. Definition: * Length is a measure of distance 2. Base Unit: * meter (m) * longer lengths = kilometers (km) * shorter lengths = centimeters (cm) 3. Instrument: * metric ruler * for very large distances: light year
