Using Metric to find Volume. Volume. Volume: desribes the amount of space an object takes up. Volume of a Solid. Volume = length x width x height Or V= l x w x h The units for a completed math calculation are cubed Ex: cm 3. Example. I have a shoe box that has the following dimensions:
E N D
Volume • Volume: desribes the amount of space an object takes up
Volume of a Solid • Volume = length x width x height • Or • V= l x w x h • The units for a completed math calculation are cubed • Ex: cm3
Example • I have a shoe box that has the following dimensions: • Length: 10 cm • Width: 12 cm • Height: 6 cm • What is the volume of the box?
Volume of a Liquid • Another unit that measures volume is the Liter. • The abbreviation is a capital “L” • 1 Liter will fill EXACTLY 1000 cm3
Volume of a Liquid • You can use the same prefixes that are used with other measurements • Milli- is often used (milliliter) • Remember, there are 1000 milliliters in a liter
Measuring with a graduated cylinder • 1. pour liquid into cylinder • 2. position yourself at eye level with the top of the liquid • 3. read the volume from the scale on the outside of the cylinder. Read the liquid at the bottom of the meniscus

Measuring with a graduated cylinder • To measure volume of a liquid, you need to know what the space between the lines represents. • 1. Subtract the numbers on any two long lines –this will give you the displacement (volume)
