The standard
Given the net of three-dimensional figures with rectangular and triangular faces, determine the surface area of these figures.
Element 6.GSR.5.2 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Geometric & Spatial Reasoning strand. It sits under standard 6.GSR.5: Solve relevant problems involving area, surface area, and volume.
What students practice
Every surface-area item prints the net. Students match nets to solids, count faces, find the area of each rectangular or triangular face, and add to get the surface area. Faces are rectangles and triangles only, and net edges are whole numbers. There are no cylinders or circles.
Where to find it
Think: paper that covers a box covers all 6 faces, so add every face.
