Net of 3-dimensional figures

A net is a two-dimensional pattern that can be folded to form a three-dimensional figure.

NET OF A PRISM

Prisms are 3-D polyedra with parallel, congruent bases.

If we break this prism into its parts we are going to have 2 bases (hexagons) and 6 lateral faces (rectangles) which make up the lateal area.


NET OF A CYLINDER

A cylinder is a 3-dimensional figure with two circular bases and a curved face.

To get the net of a cylinder, we can imagine that the lateral area of a cylinder can be "unrolled" into a rectangle with one side equaling the circumference of the circle and the other side equal to the height of the cylinder (unless it is oblique).


NET OF A PYRAMID

A pyramid is a solid all of whose faces, apart from the base, are triangular and meet at a point. The type of pyramid is determined by teh base. If the base is a rectangle, we say the pyramid is a rectangular pyramid. If the base is a square its is a square pyramid and so on.

The net of the pyramid includes the base and all the triangular faces that make up the sides.


NET OF A CONE

A cone is a solid pointed figure with a circular base. A cone is a kind of pyramid whose base is a circle.

The net of a cone is
