Title: Length and Solid Volume


1
Length and Solid Volume
  • The metric system at use!!!

2
First, We Need To Know Length!!
Length the unit of measure to determine the
distance of an object
Use A Ruler or A Meter Stick
3
What Are Those Markings??
Millimeters
Centimeters
4
How 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
Meter

Centi-
Gram
Liter
If you move right up the stairs, move the decimal
point right as many steps as you moved

Time For Solid Volume!!
2 Ways to Calculate
V L x H x W
Water Displacement

Water Displacement
  • 3 Steps
  • 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

Final Volume 48.0 mL
- Initial Volume 43.0 mL
Volume of Object 5.0 mL
9
Use The Equation!!
If the object has straight edges and can be
measured with a meter stick, use the following
equation
Length
Width
Height
Units
