In this lesson, you will learn how to represent three-dimensional figures with nets, by analyzing their faces and bases.
A net is a two-dimensional pattern of a three-dimensional figure, that can be folded to form the figure.
We will learn how to represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. We will learn how to apply these techniques in the context of solving real-world and mathematical problems.
Nets for 3-Dimensional Figures
Learn to use nets to make 3-dimensional figures
A net is the pattern made when the surface of a three-dimensional figure is laid out flat showing each face of the figure. A net is folded to make a three-dimensional figure.
3D Figures part. 1 - Nothing but nets
Drawing two dimensional nets of three dimensional figures.
3D Figures part. 2
Calculating Surface Area
Using nets and the formula for area to calculate the surface area of three dimensional figures.
Net of rectangular prism and cube
This video demonstrates the creation of a net for a cube. The folding and unfolding will be shown visually.
How to recognize the two-dimensional nets that fold into solids
Net of rectangular pyramid and triangular prism
This video demonstrates the creation of a net for a rectangular pyramid and a triangular prism from the 3-d shapes
What a Net Is (In Solid Geometry)
A net of a solid is a 2-dimensional figure which can be folded into that solid.
This video will show nets of cube, cylinder and cone.
