Surface Area of a Triangular Prism Example  resource description

Here is a really nicely illustrated step by step example of finding the surface area of a triangular prism. The area of each face is found individually and is highlighted so it’s clear which area is being calculated at each stage.

Surface Area of a Triangular Prism Example

This resource provides a worked example for calculating the surface area of a triangular prism (a 3D shape with triangular bases).


Why is a surface area important?

Understanding surface area has real-world applications:

  • Packaging: Calculating material needed to cover a product.
  • Construction: Determining paint or tile quantities for surfaces.
  • Physics: Analysing heat transfer and other scientific concepts.


How can this resource help?

This resource breaks down the process of finding surface area:

  • Formula reminder: Recalls the surface area formula for prisms.
  • Worked example: Provides step-by-step solution with a diagram.
  • Clear explanations: Guides learners through each step.
  • Free PDF download: Offers an easily accessible reference tool.


Benefits for learners:

  • Builds conceptual understanding of surface area calculations.
  • Provides a model for solving similar problems.
  • Supports independent practice and revision.

This resource is perfect for teachers introducing surface area or as a revision tool for pupils. It is also helpful for parents to support their children with geometry homework.
