#### Description:

Cross-Sections and NetsWhat if you were given a three-dimensional figure like a pyramid and you wanted to know what that figure would look like in two dimensions? What would a flat slice or an unfolded flat representation of that solid look like? After completing this Concept, you'll be able to use cross-sections and nets to answer questions like these.Lessons, videos, exercises, and text from CK-12.
