Hemera/Thinkstock
Deep snow on a roof can cause structural damage. Every winter you hear about roofs on shopping centres or arenas collapsing from the weight of accumulated ice and snow. Snow to a depth of 50 cm on a roof with an area of 100 m2 can weigh as much as 5 t (tonnes), which is the weight of a ten-passenger school bus.
How many school buses would 50 cm of snow on a roof be equivalent to if the roof were 3 times as wide and 3 times as long?
Project Connection
Modules 6 and 7 have a combined project. You should now be prepared to begin working on the surface area portion of the Module 6/7 Project: Clear the Roads! Read through the project document and make sure to pay close attention to how your project will be assessed. You can now begin working on Steps 1 to 5, which deal with surface area.
Save all your project work in your course folder to submit at the end of Module 7.
