In this Grade 5 enVision Mathematics lesson from Chapter 11, students learn how to find the volume of composite solid figures by decomposing them into two or more rectangular prisms and applying the formula V = l × w × h to each part. Students practice identifying the dimensions of each prism, calculating individual volumes, and adding the results to determine the total volume of the combined figure.
Section 1
Volume of Composite Solids by Addition
The total volume of a composite solid is the sum of the volumes of its non-overlapping component prisms. If a solid is composed of two prisms, its total volume is found by adding the volume of the first prism, , to the volume of the second prism, .
