Section 1
Identifying Components of a Prism
Property
A prism has two parallel, congruent bases and rectangular lateral faces connecting the bases.
The total number of faces equals the number of sides of the base plus .
In this Grade 6 lesson from Big Ideas Math Advanced 1, Chapter 8, students learn how to find the surface area of rectangular and triangular prisms by using nets — two-dimensional unfolded representations of a solid — to calculate and sum the areas of all faces. The lesson covers key vocabulary including surface area and nets, and walks students through worked examples using dimensions to compute total surface area in square units. Students apply these skills to both prisms with rectangular and triangular bases, connecting to Common Core standard 6.G.A.4.

The total number of faces equals the number of sides of the base plus .
Section 2
Finding Surface Area Using Nets
A net is a 2D pattern that can be folded to form a 3D solid. To find surface area using nets:
(1) identify all faces in the net;
(2) calculate the area of each face;
(3) sum all areas: Surface Area =
