solve problems involving the volume and surface area of right prisms and cylinders using appropriate units

Elaborations

• 1 analysing nets of objects to generate short cuts and establish formulas for surface area
• 2 determining the amount of material needed to make can-coolers for a class fundraising project and working out the most cost-efficient way to cut out the pieces
• 3 finding different prisms that have the same volume but different surface areas, making conjectures as to what type of prism would have the smallest or largest surface area
• 4 investigating objects and technologies of First Nations Australians, analysing and connecting surface area and volume, and exploring their relationship to their capacity
