## Sides

The side encounters of a prism space parallelograms(4-sided forms with opposite political parties parallel)## 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:

**The stack deserve to lean over, but still has actually the same volume**

## 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**.
