Lesson 14

Working with Pyramids

Lesson Narrative

Students calculate the volume of several pyramids, and they work backward to find possible dimensions of a pyramid given its volume. Students make use of structure (MP7) when they select dimensions that combine to create a particular volume result.

Learning Goals
