Volume

Prisms and Cylinders

Volume of a Prism

 A prism is a solid object with:

•identical ends•flat sides•and the same Cross Section all along its length !

                            

A cross section is the shape made by cutting straight across an object. The cross section of this object is a triangle ..... it has the same cross section all along its length ...... and it's a triangular prism

Bases

The ends of a prism are parallel and each one is called a base.

Sides

The sides of a prism are Parallelograms(4-sided shape with opposites sides parallel)

A prism is a polyhedron, which means all sides are flat

No Curved Sides!

So a Cylinder is not a prism

Volume of Prism

The Volume of a prism is the Area of the Base times the Length

Volume = Area x Length

Volume of Cylinder

The Volume of a Cylinder is found the same way

Volume = Area x Length

Volume = Length

Area

Length

I can calculate how much playdoh comes out of the fun factory by calculating area of the shape x length
