Understanding the surface area of three-dimensional shapes is an important part of Year 8 Math. Below, you'll find the formulas to help you calculate the surface area of some common 3D shapes.
A cube is a shape with six equal square sides.
A rectangular prism has six rectangular sides, and opposite sides are the same.
A cylinder has two circular ends and a curved surface that connects them.
A sphere is a perfectly round shape.
A cone has a circular base and a pointy top.
Calculating surface area isn’t just for schoolwork; it’s useful in real life too!
Knowing these formulas is key for solving geometry problems and using math in everyday life. Students should practice these formulas with different sizes to build their math skills and confidence.
