# Surface Area of Square Based Pyramids

Students learn how to use net drawings and apply Pythagoras' Theorem to calculate the total surface area of square based pyramids.As learning progresses students are challenged to calculate the total surface area of composite solids including frustums.
##### Differentiated Learning Objectives
• All students should be able to calculate the total surface area of a square based pyramid using a net drawing.
• Most students should be able to calculate the total surface area of a rectangular based pyramid using Pythagoras' Theorem.
• Some students should be able to calculate the total surface area of composite shapes including frustums.
