Find the surface area and volume of composite shapes.
Introduction
Previously in Secondary 1, we looked at the surface area and volume of prisms and cylinders. In Secondary 2, we will examine 3 more 3D shapes: Pyramids, Cones and Spheres.
Architecture
Geometrical shapes like cones are used in the design of buildings like Wheelock Place in the image above.
Planet Earth
Planets in our Solar System can be modelled as spheres.
