Scaling Two Dimensions

Open Up Resources 40 min(s)

Use representations of functions to describe the relationship between the volume of a rectangular prism and two of its dimensions when one dimension is fixed. Use representations of functions to describe the relationship between volume and a dimension that is squared. Use this representation to notice that if you change one such dimension by a scale factor , the volume changes by the scale factor. Learning targets: students can explain in my own words why changing the radius by a scale factor changes the volume by the scale factor squared.
