Volume of Cube - Build-Up & Decompose


Learning Objectives:
Understand why the volume formula for a prism is length*width*height, by building a prism.
Use the group, explode, copy, paste, move, entity information (volume), and dimension tools.
Common Core State Standards - Mathematics - 6.G.2

Step 1. Create a single 1x1 cube, duplicate the cube four times, snap them together to create a 1x1x4 prism.
Hint - Drag a corner point of one cube to the corner point of the second cube. You should see them line up correctly and snap together.
