Lateral & Total Surface Area Using Nets

T.i.P.S.

For this standard, students will need to be able to determine both lateral and total surface area from a shape's net, rather than using a surface area formula. Students should connect the concept of finding the area of composite figures to finding the total surface area.

Example

Billy is creating a box to ship his model airplane for a contest. It will ship best in the shape of a triangular prism. How much cardboard will Billy need to make his box in the shape of a triangular prism using the following known measurements?
