Examples, solutions, videos, and lessons to help Grade 6 students 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. Apply these techniques in the context of solving real-world and mathematical problems.

Common Core: 6.G.4

### Suggested Learning Targets

**6.G.4 Surface Area and Nets**

How to represent 3-d figures with nets and use the nets to find the surface area?

A net is a flat picture of a 3-d shape.

Surface area is the sum of all the faces of an object.

Example:

Find the surface area of a rectangular prism with length 3, width 2 and height 2. Use a net to help.

**Nets of 3D-Shapes**

What is the net of a shape?

A few example nets together with their 3D counterparts.

Nets of cube, triangular prism, square-based pyramid
