Surface Area of Prisms

Students use net drawings and 3D representations to calculate the surface area of prisms made from parallelograms, triangles and trapezia.  As learning progresses students use composite areas to find the surface area of prisms where the cross-section is a regular polygon.

The start of the lesson recaps finding the area of a trapezium and converting between metric units of length and area.  At the end of the lesson students find the surface area of a pentagonal prism.

Differentiated Learning Objective

  • All students should be able to calculate the surface of a rectilinear prism.
  • Most students should be able to calculate the surface area of a prism.
  • Some students should be able to calculate the surface area of a prism with a composite cross-section.
