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: 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

Look at this…

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)
