Surface Area: Introductory Exercises
Take a few minutes to interact with the rectangular prism shown here. After doing so, create one that has a length = 4 units, width = 5 units, and height = 3 units.
How many square units (i.e. "squares") appear on 1 pink face?
How many square units (i.e. "squares") appear on 1 gold face?
How many square units (i.e. "squares") appear on 1 white face?
