Title: Length and Solid Volume
1Length and Solid Volume
- The metric system at use!!!
2First, We Need To Know Length!!
Length the unit of measure to determine the
distance of an object
Use A Ruler or A Meter Stick
3What Are Those Markings??
Millimeters
Centimeters
4How Can We Change From Centimeters to
Millimeters, etc. ?
If you move left down the stairs, move the
decimal point left as many steps as you moved

6Time For Solid Volume!!
2 Ways to Calculate
V L x H x W
Water Displacement
7Water Displacement
- Take an original volume of the
- water in the graduated cylinder
2. Place the object in the water
3. Observe the new volume and subtract the
original volume from the new volume

9Use The Equation!!
If the object has straight edges and can be
measured with a meter stick, use the following
equation
