A community centre is creating a 3D-printed stand for a tablet.
The designer models the stand in a CAD app. The stand is made from two joined solids:
In the side view (lengthwise), the triangular cross-section of the support is a right triangle with:
The support has the same width as the base (9 cm). The support is positioned so that its 10 cm base sits fully on the top of the rectangular base.
The CAD app can automatically calculate volume and can also generate a “slice preview” that shows the cross-section area at a given width.
Describe how you could use the CAD app’s “slice preview” to confirm the cross-section area of the support (triangular prism) at any point across its 9 cm width, and state what that area should be.

In Unit 3 students further develop and enhance their numeracy practices to make sense of their personal, public and vocational lives. Students extend their mathematical skills with consideration of their local, community, national and global environments and contexts, and the use and evaluation of appropriate technologies. These units provide students with a broad range of mathematical knowledge, skills and understanding to solve problems in real contexts for a range of workplace, personal, further learning and community settings relevant to contemporary society.
In this area of study students learn to recognise and name a range of two-dimensional shapes and three-dimensional objects. They classify, manipulate, represent and construct a range of simple and compound shapes in diagrammatical and concrete forms. Students also become familiar with the different characteristics and properties used in classifying shapes.
