Solve Surface Area Problems
Lesson Goal is to be able to find the area and surface area of 2D and 3D composite shapes.
Composite shapes are a combination of two or more geometric shapes.
Steps to Solve a Surface Area Problem
Break the composite shape up into shapes you know such as rectangles, triangles, and circles.
List all the dimensions you know and surface area formulas you will need.
Calculate the surface area of each shape.
Add the surface area values for each shape.
