VocabularyVolume: Volume is the space within a 3-Dimensional Shape.
Surface Area: Surface Area is the space around a 3-Dimensional Shape 3-Dimensional Objects: 3-Dimensional shapes are shapes that have length width and depth. |
Today's Target: Practice calculating surface area for rectangular prisms and triangular prisms
|
Reminder - What is Surface Area?
On a 3D object, surface area would be considered the perimeter. It is the total area around the shape.
If you had beach ball, the surface area would just be the outer layer of the ball that you see. Surface area and Volume are the two important key terms when understanding 3D shapes. Calculating the surface area means finding each Area and adding all totals together. |
Example
This example is just for reference because all these number (at first glance) can be really, really, intimidating. Lets do some examples together first.
