About This Worksheet

This medium-level worksheet contains 14 problems designed for 5th Grade students practicing volume of composite figures. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.

Real-world structures are rarely simple rectangular prisms. Learning to decompose complex figures develops flexible three-dimensional reasoning and directly applies to architecture, product design, and engineering.

  • Decompose a composite 3D figure into non-overlapping rectangular prisms
  • Find the volume of each prism and add to get the total
  • Solve real-world problems involving composite volumes
  • Identify multiple ways to decompose the same composite figure
  • Check by estimating the overall dimensions
