Volume The amount of space an object takes up

3 ways to measure volume Liquid Volume –Graduated cylinder mL Volume of a Regular Solid –Length x Width x Height cm 3 (3 sides, so it’s to the 3 rd power ) Volume by Displacement –Archimedes Bath tub/ Naked Guy/ Eureka

Volume by Displacement Get the volume of an Irregular Object –Take a known volume of water example 50 mL –Place the object in the water Read the water level 80 mL –Subtract the smaller number from the larger number 80mL - 50mL = 30mL

Mass Amount of “stuff” in an object The amount of matter in an object

Density The amount of matter in a given space –The amount of “stuff” in an area –No way to measure it Must be calculated Mass / Volume –g/mL or g/cm 3
