Unit 5, Lesson 18# Determining Surface Area of Three-Dimensional Figures

EngageNY 45 min(s)

Students determine that a right rectangular prism has six faces: top and bottom, front and back, and two sides. They determine that surface area is obtained by adding the areas of all the faces and develop the formula. Students develop and apply the formula for the surface area of a cube. In order to complete the Opening Exercise, each student needs a copy of the shape template that is already cut out.
