On this page you will find a Grade 8 Mathematics Term 3 project worth 50 marks, completed in one hour, on the total surface area of 3D figures. Learners recall area formulas for squares, rectangles, and triangles before applying them to calculate the areas of labelled shapes. The three-question paper requires clear working and diagrams to support each answer. Instructions permit an approved scientific calculator for later calculations. This project helps Grade 8 learners apply area formulas to concrete geometric problems as part of their Term 3 Mathematics work.
The following document, Mathematics Gr 8 Project Term 3 1.pdf, is the full document.

Grade 8 Mathematics Term 3 Project on Surface Area PDF jjtfph
“The outside area of a 3D object is the total area of the levels of the object.” “An opened view of a 3D object is called the net of the object.” “The total surface area (TSA) of the cube… TSA = area of square 1 + area 2 + … + area 6.”
Grade 8 Mathematics Total Surface Area project (50 marks, 1 hour); Question 1 – area formulas for squares, rectangles and triangles; Question 2 – identifying nets of 3D figures; Question 3 – calculating total surface area of a cube and rectangular prism.
State and apply area formulas for squares, rectangles and triangles; identify the correct net for a given 3D shape; calculate the total surface area of cubes and rectangular prisms; apply the theorem of Pythagoras to find a triangle’s height.
