Big Ideas:
We can find the volume of a composite solid by finding the sum of the volumes of its components.
Volume is a unique attribute of solids that explains how much space an object takes up.
This lesson builds on students' work with finding volume using unit cubes and formulas. The task uses a real-world problem to contextualize the idea that volume is additive. Students are asked to determine the volume of a composite figure by adding layers with a variety of dimensions to find the total volume. The mathematical concepts in this lesson build towards student work with finding the volume of composite prisms.
Vocabulary:
volume, layers, additive, composite solid
