Sides
These are all Prisms:
| Square Prism: | Cross-Section: |
 | |
| Cube: | Cross-Section: |
 | |
| (yes, a cube is a prism, due to the fact that it is a squareall follow me its length)(Also see rectangle-shaped Prisms ) | |
| Triangular Prism: | Cross-Section: |
 |  |
| Pentagonal Prism: | Cross-Section: |
 |  |
Example: This hexagonal ice crystal.

It looks like a hexagon, but due to the fact that it has some thickness that is in reality a hexagonal prism!

Regular vs rarely often, rarely Prisms
All the previous examples are Regular Prisms, because the cross ar is constant (in various other words the is a form with equal edge lengths, and also equal angles.)
Here is an instance of an Irregular Prism:
| Irregular Pentagonal Prism: | ||
 |  | |
| Cross-Section | ||
| It is "irregular" due to the fact that thecross-section is no "regular" in shape. |
Right vs slope Prism
When the 2 ends are perfectly aligned it is a ideal Prism otherwise that is an slope Prism:
Surface Area that a Prism
Example: What is the surface ar area that a prism wherein the base area is 25m2, the base perimeter is 24 m, and also the size is 12 m:
Volume of a Prism
The Volume that a prism is the area the one finish times the length of the prism.

Volume = base Area × Length
Play through it here. The formula likewise works when it "leans over" (oblique) however remember that the elevation is at ideal angles to the base:
And this is why:
More around The side Faces
Theside facesofaprism space parallelograms (4-sided shape with opposites sides parallel)
A prism have the right to lean to one side, making that an slope prism, however the two ends room still parallel, and also the side faces are tho parallelograms!
But if the two ends are not parallel the is not a prism.
