The amount of matter in a given volume of an object (how tightly packed together the particles are) Least Greatest D = M/V Graduated Cylinder Metric Ruler Triple-beam balance D M V

g/mL g/cm 3 D = M/V D = 150g/V (V = 1 x 5 x 2) D = 150g/10cm 3 D = 15g/cm 3

D = M/V D = 80g/V V = = 25 mL D = 80g/25 mL 3.2 g/mL

V = M/D V = 44g / 5.5 g/cm 3 44 g 8 cm 3 V = L x W x H 8 cc = L x W x H 8 cc = 2 x 2 x 2
