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.
7.9 Expressions, equations, and relationships. The student applies mathematical process standards to solve geometric problems. The student is expected to:
(D) solve problems involving the lateral and total surface area of a rectangular prism, rectangular pyramid, triangular prism, and triangular pyramid by determining the area of the shape's net
