Making Nets to Represent Rectangular Prisms

​

Poll

What similarities do you notice between the length, width, and height of the prism, and the dimensions given in the net?

• The sides have the same dimensions

• The bottom and top have the same dimensions

• The front and back have the same dimensions

• The only ones that do not have 3 as a dimension are the front and the back

• The parts of the net that would be opposite or parallel to each other, when wrapped around a rectangular prism, have the same dimensions

​

​

The rectangular prism has a length of 10 cm, a width of 6 cm, and a height of 8 cm.

We will learn how to draw and label a net to represent a rectangular prism.
