How to find the surface area of a rectangular prism plus NCTM

How do we find the surface area of a 3-dimensional object? What is the surface area of a rectangular prism? How does one approach such math quandaries without languishing in the pit of despair and self-loathing?







Are these not the questions that keep us awake at night? That flood our conversations? Ok, maybe not! But that doesn’t mean they aren’t crucial for our kids and their math classes 🙂 We’ve spent time finding the area of a rectangle. If you haven’t watched that lesson, then pause, and go HERE.

Now, it’s time to move from 2-dimensions to three dimensions!










In less than 12 minutes, Amy teleports us to the 3-dimensional world of the surface area of rectangular prisms! Along with this, she illuminates an incredible tool the National Council of Teachers of Mathematics (NCTM) has available. Check it out here.

So what are you waiting for! It’s time for multidimensional travel
