Volume as additive

Mathematics · Measurement · procedural

Recognise volume as additive; find volumes of composite solid figures made of two or more non-overlapping right rectangular prisms

Sign in to track this

What mastery looks like

  • Decompose an L-shaped solid into two cuboids and calculate total volume
  • Solve a real-world problem requiring the volume of a composite figure (e.g. a step-shaped structure)
  • Explain why splitting a composite solid into rectangular prisms allows calculation of total volume

Check your understanding

If an L-shaped swimming pool is made of two rectangular sections, can Volume as additive find the volume of each section separately and add them to get the total volume of the pool?
