The following formula sheet sums the whole topic up: Measurement Formula Sheet |
1D: PerimeterPerimeter is the distance around a two dimensional shape
Rules:
Example: |
2D: AreaArea is how we thinking about how much space something takes in two dimensions such as comparing how much land one property takes up versus another.
We will look at simple Area as well as Surface Area which is the area of a 2D surface wrapped around a 3D shape. Example |
3D: VolumeVolume measures how much 3-dimensional "space" an object takes up.
